De 298,080 opiniones, los clientes califican nuestro node.js Developers 4.9 de un total de 5 estrellas.I maintain a JavaScript/Node.js web application built with React and one feature has started misbehaving. I will provide the repository link, clear steps to reproduce, the current versus expected behaviour, and any relevant environment details. Your task is to reproduce the issue, isolate its root cause, deliver a concise fix that touches only the code involved, and verify the result with a test or other reproducible check. To keep things tidy I need: • the corrected code committed to the existing branch • a test or manual verification script that proves the fix works • a brief summary (one-paragraph release note or commit message) outlining what changed and why Please let me know how quickly you can turn this around when you respond.
I need a self-hosted identity-verification flow focused exclusively on U.S. driver’s licenses. The user journey is simple: they upload clear front-and-back images, your service analyses the images for authenticity (holograms, microprint, barcode consistency, etc.), extracts the data fields, and returns a verification status plus the parsed data in JSON. The core task is to build this as a RESTful service and wire it into my existing backend. I’m comfortable exposing webhooks or consuming your API from Node.js, Python, or Java, so pick the stack you work fastest in—as long as the integration points stay standard (HTTPS + JSON). Please rely on proven libraries or services for image analysis (e.g., OpenCV, AWS Rekognition, or any SDK you prefer) and keep everything packag...
Project Overview: I have a working prototype of a multi-channel seller management app called RIVA. It allows sellers to manage product listings, pricing, and inventory across multiple platforms (Meesho, Flipkart, Amazon, Myntra) from a single dashboard. The current MVP has a Node.js/Express backend, SQLite database, OTP-based authentication, a basic AI assistant chat widget, and an Android APK wrapper built with Capacitor. It’s currently deployed on Render.com. I’m looking for an experienced developer to take this from prototype to a stable, production-ready product. What I need help with: Review and refactor the existing backend (Node.js/Express) for scalability and security Fix known issues with the Android APK (connectivity/WebView configuration problems) Improve the data...
I’m ready to bring a multi-tenant, web-based Fleet Management platform to life, aimed specifically at truck operations. The core of the build revolves around three functions that must feel seamless to the end user: live vehicle tracking, automated maintenance scheduling, and full driver management. The application has to talk directly to common GPS tracking systems so every truck shows up in real time on a map and pushes location data into our database for analytics and alerts. I also need a clean two-way integration with popular accounting software (think QuickBooks or Xero) so mileage, maintenance costs, and driver expenses flow straight into the books without manual import. Fuel-card links and other add-ons may follow, so keep the architecture open for additional webhooks and A...
I need a developer who can take full ownership of opening, configuring, and technically integrating accounts for thirty-five separate payment providers on my e-commerce sites. All integrations will run on standard website stacks, not mobile or desktop apps, and each gateway must successfully process both credit/debit card transactions and the cryptocurrency options that the providers allow. Here’s what the job looks like from my side: I will supply access to the sites, the list of providers, and any required corporate documentation. You will handle the account applications where needed, obtain and secure API keys or SDKs, install the gateways, map the required webhooks, and make sure that successful, failed, and refunded payments are reported correctly in the site’s back-offic...
I am looking for an experienced full-stack developer to finish, debug, and prepare for production an existing fragrance web application called Scent Layer. This is NOT a project that needs to be built from scratch. The application already exists, the source code is on GitHub, the frontend is deployed and working, the backend is running, and the PostgreSQL database has already been configured. Current technology stack: - React + Vite frontend - Node.js + Express backend - PostgreSQL - Prisma ORM - Anthropic Claude API / AI features - Stripe payments - Email integration - JWT authentication - GitHub - FastComet / cPanel hosting Current status: - Frontend is already live and working. - Backend/API has been deployed. - PostgreSQL database is created and connected. - Prisma database structure i...
I'm the founder of NILQuant, an independent record for NIL deals in college athletics. We're looking for a qualified, independent reviewer for a scoped technical review of our core verification engine before its first production release. Scope (summary; full scope attached): - Rebuild our PostgreSQL database from its migration files on your own machine and repeat our test suite and reproduction kit - Check append-only history, two-person release controls, fingerprinting (SHA-256), school-to-school data isolation and a scoped verification API - Test the hosted demo with six test accounts (no admin access) and try to break the controls - Confirm our outside timestamping and write-once storage settings - Written findings, one retest round and a signed scoped conclusion All data is...
I’m building a MERN-based application and the heart of the project is real-time communication. Everything else can evolve, but I need the live connection layer architected and working flawlessly first. Here’s what I’m after: a React front end that talks to a Node/Express API through WebSockets ( or native WS—your call) so users can interact instantly without refreshing the page. Think low-latency updates that feel as snappy as Slack or Discord. Back-end code should be clean, modular, and ready to plug into a Mongo (or alternative) data store once the wider feature set is finalised. For now, persistence can be lightweight, but the structure must anticipate scaling to a full database layer. To keep us aligned, I’ll consider the work complete when: • A ...
I’m ready to launch a brand-new cryptocurrency with a fixed maximum supply of 10 billion coins and I don’t want to piggy-back on Ethereum, BSC or Polkadot—I need an independent chain built from the ground up. The core purpose of the coin is to power smart-contract execution, so the chain architecture, virtual machine and fee model all have to be optimized for that use-case. What I already have in mind • Tokenomics: 10 billion total supply, no more, no less. • A smart-contract–friendly environment that can rival EVM chains in speed and cost. • Room to evolve into DeFi utilities later on. Where I need your expertise I’m looking for end-to-end technical guidance and implementation: choosing or designing the right consensus layer, writing ...
I’m building an intelligent product whose sole purpose is to tutor adult learners in Science. The vision is a conversational, AI-driven experience that diagnoses gaps, adapts in real time, and keeps motivation high through engaging explanations and practice. Here’s how I picture the workflow: a learner signs in, answers a brief diagnostic, then interacts with an adaptive chat interface powered by a fine-tuned large-language model. The back-end tracks progress, surfaces targeted exercises, and serves concise concept refreshers with embedded visuals, simulations, or short quizzes. Think of a personal tutor available 24/7, able to shift from basic principles to advanced applications as the user’s mastery grows. Key elements I need you to handle • Natural-language tu...
I’m rolling out a web-based SaaS platform dedicated to project management and I’m looking for a software engineer who can take it from concept to a production-ready application. The first release must nail two pillars: robust task management and smooth team collaboration. Everything—from the database schema to the front-end interactions—should feel fast, intuitive, and ready to scale. What I have in mind • A clean, responsive web interface that lets users create projects, break them into tasks, assign owners, set statuses, and track progress in real time. • Built-in collaboration: threaded comments, @mentions, file attachments, and live updates so teams don’t need to keep refreshing a page. • Multi-tenant architecture with role-based perm...

I run a sports website and want to embed reliable live-score data without constantly switching providers. I’m after an API (or an existing feed you have access to) that pushes real-time cricket scores—specifically for One Day Internationals and T20 matches—with refreshes every single minute. What I need from you: • A stable, permanently available endpoint that I can query via JSON or XML. • Clear documentation showing all request parameters and sample responses for the ODI and T20 score calls. • An example call integrated into a simple PHP, Node, or Python snippet so I can verify the feed on my server. • Assurance that the feed covers all major international fixtures in those two formats and remains active season after season. Once I&rsqu...
I already run a live arbitrage bot that talks to Binance, Coinbase and Kraken, but several core pieces need a professional overhaul. The idea is to keep the current codebase yet refine it so it can scale safely and catch more profitable spreads. Here is what I need you to improve: • API integration – tighten rate-limit handling, add fail-over logic and make it easier to plug in new exchanges later. • Arbitrage strategy – optimise the price-discovery loop, latency, and order-routing so opportunities are captured faster. • Risk management – add dynamic position sizing, max-drawdown guards and configurable circuit breakers. The project is written mainly in Python, though I’m open to integrating performant Node.js or Go micro-services if you feel i...
I’m looking for a reliable developer who can jump into my existing repository, open clean pull requests, and help me keep the site fresh. The most immediate need is regular content updates—editing copy, swapping images, and adding the occasional new section—but I often discover small bugs or UX tweaks along the way, so being comfortable fixing those in the same branch is essential. You’ll work through GitHub and its Actions pipeline; once a PR is approved it should deploy smoothly to my AWS stack. If something fails in staging, I’ll expect you to trace the issue and push a quick patch. Please be ready to show a few GitHub repositories where you handled similar CI/CD flows. AWS experience (EC2, S3 or Amplify—whatever tools you prefer) and clear English ...

Finish and release four existing apps (React Native/Expo, Node/Postgres, React) for a US-based IoT vending device. The build work is done: these apps took about six months to build and are functionally complete. This job is verified production release, not a new build, and it is priced that way. WHERE IT STANDS The four apps are built and functionally complete: a customer app (React Native/Expo), a service app (React Native/Expo), a backend (Node/Express/Postgres with Stripe) and a React admin dashboard. Tens of thousands of automated tests have been run across the codebases. Each has existing CI, open pull requests, a written release procedure and detailed evidence. What remains is acceptance on real systems: production, real phones and the payment provider. THE WORK 1. Verify the exact...

I’m planning a full-scale matrimony platform and need a seasoned full-stack developer to take it from first commit through live deployment. The site must feel effortless on mobile and desktop, load quickly, and follow best-practice security patterns so members feel safe sharing personal information. Core features I need built and polished: • Robust user registration with Email and Password authentication, backed by secure hashing and account-recovery flows. • Detailed member profiles, including photos and bio fields, plus an automated verification process that checks IDs or similar evidence before a profile goes live. • Advanced search driven by filters for age, location, and interests so users can narrow matches intuitively. • Real-time or near-real-time m...
I need a lightweight web application that lets prospective “boyfriends” sign up and publish a public-facing profile. The core scope, for now, is limited to profile creation only—no chat or booking features yet—so the entire build can stay clean and focused. Key elements I have to see on every profile are: • Multiple photos with an easy upload/replace flow • A short bio or description field • Separate sections for interests and hobbies • A dedicated height field (simple number + units) From the visitor side, anyone landing on the site should be able to browse the published profiles in a tidy, searchable gallery. On the back end, each boyfriend needs a secure login so he can edit or hide his own profile without touching anyone else’...

I handle a continuous stream of small-to-mid-size sites that have to be built and cared for from the ground up. Every project is coded directly in HTML5, CSS3 and modern JavaScript—no CMS layers—so I need a developer who is completely comfortable in a pure front-end environment and enjoys keeping code clean, semantic and lightweight. Most weeks you’ll receive a mix of tasks: standing up new responsive sites from supplied designs, extending existing pages, tightening performance, or squashing layout glitches before they reach production. All work moves through Git branches, with short, well-described commits and pull-request reviews; deployments are handled over simple static hosting or lightweight node servers. Deliverables for each assignment will include: • Pixel...
We're hiring versatile senior engineers who own delivery across the full SDLC and have genuinely adopted an AI-assisted way of working. You'll turn ambiguous product direction into production software in days, not weeks, inside a regulated payments environment (DORA, PCI DSS, SOC 2, EMI regulations, GDPR). Our controls shape the SDLC, from change management and approvals to testing evidence and audit trails. We want engineers who work smart within them, not around them. The selection process is hands-on: be ready to show your AI-assisted delivery, not just describe it. What you'll do - Own features end to end: design, build, test, deploy and support. - Work across a polyglot stack (Ruby, Node, Go) plus modern frontend. - Use AI tooling as a core part of building, reviewing...

I need an advanced data-feed solution that plugs straight into the Quotex platform and streams real-time market prices for binary instruments without delay or throttling. My priority is price accuracy and low-latency delivery; trade volumes or macro-economic releases are not required at this stage. Here is what I have in mind: • Direct, continuous price updates for the binary markets available on Quotex • Integration via the most efficient method you can offer (API, WebSocket, or a custom bridge) • A lightweight interface or script so I can quickly verify tick-by-tick values against the native Quotex chart • Clear, commented code and a short setup guide so I can redeploy the feed on another machine if needed Acceptance criteria • Latency consistently under ...
I’m building a browser-based control panel for my VPS and already have a partial design plus a rough style guide. I now need the remaining screens and their front-end logic completed so the whole interface feels polished and consistent. The project is purely web-based. I’m open to whichever modern framework you feel most comfortable with—React, Vue.js, Angular or another comparable stack—so long as the final bundle is lightweight, responsive and easy to extend. You will receive the existing design files, component snippets and API endpoints; your task is to finish the missing pages, connect the UI to the provided JSON endpoints and make sure everything renders smoothly across the latest Chrome, Firefox and Safari versions. Acceptance criteria • Every planned ...
I’m ready to retire Firebase and stand up a classic Node.js + MySQL stack behind my existing React front-end. The goal is a like-for-like migration: all calls that currently hit Firebase should instead be served by a new RESTful API built with Express, with data stored in MySQL. Database I already have part of a MySQL schema in production, but several collections live only in Firebase. You’ll need to merge the two worlds—re-use what exists where it makes sense and design fresh tables when the Firebase structure doesn’t map cleanly. I’ll provide the current schema dump and access to the Firebase JSON export so you can plan the mapping. Authentication User sign-in must move from Firebase Auth to running on Node.js. Standard email/password flow is enough f...
I’m assembling a cross-platform solution that links university students to corporate recruiters through three core experiences: • Student profiles that hold rich, searchable content—at launch this means text descriptions and images, with embedded project links and dynamic skill tags. • A job board where students slice results by role type, location, domain and salary. • A Kanban-style ATS for recruiters, mirrored by a real-time status dashboard on the student side. Authentication is social-only for now, using Google OAuth. Please structure the auth layer so additional providers or SSO can drop in later without a refactor. Tech stack expectations Web: React.js or Next.js. Mobile: Flutter or React Native—feature parity with the web version. Backe...
I need an Android application that lets my clients handle every routine tax task from a single, simple interface. Core workflow • Secure sign-up and log-in with email and password only—no social or guest access. • A clean, minimal home screen that immediately shows the user’s active GST and Income-Tax jobs, their current status (e.g., “Draft”, “Submitted”, “Acknowledged”), and any pending actions. • Separate modules for GST Registration & Return Filing and for Income-Tax Filing, each guiding the user step-by-step, saving progress locally and syncing to the server in real time. • A service dashboard where customers can review completed filings, download acknowledgments, view fee invoices, and raise support tick...
I have two parallel needs and would like to tackle them in one cohesive engagement. First, I need a job-posting platform built from scratch. The core flow should let employers register, create and manage vacancies, and let candidates build searchable profiles, apply, and receive status updates. A clean, mobile-responsive interface, secure authentication, and an admin dashboard for moderation and analytics are all essential. Feel free to suggest the best tech stack; I’m open to anything from a classic LAMP setup to a modern React + Node or Laravel solution as long as it remains scalable and easy to maintain. Second, I have a catalogue of product images that require professional Photoshop retouching. Consistent backgrounds, balanced lighting, dust removal, and colour accuracy are k...
I need ReCAPTCHA v3 added to my login page immediately to stop the persistent spam attacks we have been seeing. The Google console keys are ready, the codebase is clean, and I can give you SSH or admin access the moment we start. Your task is simple: insert the v3 script, call the site-key on the login form, verify the token server-side, and return a clear success/fail response so genuine users log straight in while bots are blocked silently. Please keep the existing design intact and avoid adding extra fields or friction for real users. I’m aiming to have this implemented, tested, and live within an hour of awarding—so only reply if you are confident you can do this fast using standard Google reCAPTCHA v3 methods (JavaScript client-side plus PHP, Node, or equivalent server v...

I’m ready to launch a cryptocurrency exchange built specifically for newcomers, so every decision—in design and in code—needs to feel effortless for someone making their very first trade. Here’s what must be in place from day one: • A truly user-friendly interface that shepherds users from account creation to their first purchase without exposing them to intimidating order books. • Educational resources integrated right into the flow—tooltips, short videos, and concise articles that answer questions in context. • Instant buy/sell functionality so a beginner can move from fiat to crypto (and back) in just a few clicks. The exchange must handle a wide range of cryptocurrencies, not just the usual Bitcoin and Ethereum. A single wallet ex...
I want to roll out a full-featured WhatsApp Customer Support Assistant that will do three things exceptionally well: 1. Instantly answer customers with automated replies covering our most common FAQs, real-time order status updates, and personalized messages pulled from existing customer data. 2. Hand off the conversation to a live support agent whenever the issue needs human attention, keeping the entire chat history intact. 3. Prompt customers for quick feedback once the interaction is closed so we can measure satisfaction and improve our service. To make the assistant truly useful, it has to plug straight into our current stack: the CRM for customer records, the order-management system for status lookups, and the knowledge-base system for curated answers. I’m open to the tec...

I run a market-research agency and I need a developer who can turn raw survey results into an easy-to-navigate, web-based dashboard and also set up a clean redirect flow for respondents once they finish a study. Here’s what I’m after: the dashboard should present the data primarily as sortable, paginated tables or lists. I want anyone on my team to be able to slice the data on the fly with interactive filters—think demographics, wave, device type—without waiting for a page refresh. Charts and maps aren’t essential right now; clarity in table form is. The source data will arrive in CSV or via API from our survey platform, so you’ll need to build (or hook into) an automated pipeline that fetches the latest file, stores it securely—MySQL, Postgr...
