I’m replacing a collection of spreadsheets with a single, web-based system dedicated solely to Order Management inside our warehouse. The application must let my team: • track every order from creation through dispatch • manage the pick-pack-ship workflow for fast, accurate fulfillment • record and process returns, automatically updating the order’s status Nothing else—no stock tracking or analytics—just a streamlined order lifecycle hub that staff can open in any modern browser. I’m comfortable with mainstream tech stacks (Laravel, Django, Node, React, Angular, PostgreSQL, MySQL), so choose whichever you’re fastest with as long as the code is clean, documented, and REST-friendly for future integrations. Deliverables will be: 1....

My MongoDB Atlas cluster connects instantly through Compass, yet the same connection string refuses to cooperate inside my React project. The URI is tucked away in an environment variable, but at runtime I receive a generic “connection string” error and no data appears. I need someone to: • review how I’m importing the .env values and verify the string syntax • confirm the driver / library I’m using from the React side (or its Node-based API layer) is configured correctly for an Atlas URI • diagnose any authentication, whitelisting, or network nuances that Compass might mask • deliver a working example and a brief explanation so I can replicate the fix across environments Once the project builds and fetches data from Atlas without throwi...

I’m kicking off the creation of a brand-new web application and need a programmer who can guide the project from first commit to production release. You’ll take my concept and implement both the user-facing front end and the server-side back end, then deploy everything to a live environment. You are free to choose a modern tech stack—React, Vue, or plain JavaScript on the front end; Node.js, Django, or a comparable framework on the back end—so long as it results in clean, secure, well-documented code. Database design, API integrations, user authentication, and responsive UI are all part of the scope. I already have wireframes and a feature list ready to share once we start. Deliverables • Fully functional web application that matches the provided feature li...

I already have a production-ready library management platform running on a front end with a NestJS API, containerised with Docker and deployed on AWS (files are stored on S3). The missing piece is a compact student-tracking module that: • scans a student’s unique QR code on entry and exit • records the exact timestamps, the library section they visit, and calculates total duration of stay • appears seamlessly inside the current interface (no separate UI) The work involves adding the relevant pages/components in , extending the NestJS services and database schema, wiring in any AWS resources you need, and shipping the whole thing with full Jest unit/integration tests. Code quality must match the existing clean, typed, linted codebase; every new container or scr...

Project Title Finish and Launch + Firebase Evangelism App (TWSS) Overview I need an experienced full-stack developer to finish, debug, and launch a web-based evangelism app called The World Shall Be Saved (TWSS). The project is mostly built but currently unreliable due to an incomplete backend change (Firestore originally, partial PostgreSQL work). There is an older version that worked and a newer branch with partial fixes. Your job is to get it stable, working end-to-end, production-ready, and prepare it for release on Google Play and Apple App Store (via the simplest reliable approach based on the repo). Current Stack • Frontend: • Auth: Firebase Authentication • Database: Firestore (original), partial migration toward PostgreSQL (incomplete) • Google APIs: Googl...

The codebase is a React front end that relies on Supabase for authentication, data storage, and real-time updates. A series of stubborn bugs have crept in—misfired auth callbacks, occasional data mismatches after writes, and visibly broken UI states when the websocket drops. Your first mission is to isolate and eliminate those issues so the app runs cleanly, with no console errors and all existing unit tests green. Once the core bugs are gone, I’d like a quick pass on the database schema (a couple of tables need index tweaks and a foreign-key adjustment) and help preparing a production deployment workflow. The stack is already wired to GitHub; I deploy to Vercel, but I’m open to your preferred routine as long as rollbacks are painless. Everything needs to be wrapped up ...

Refresh Token Fix. Firebase Auth Refresh Token Setup (Bubble + Node.js Cloud Functions) Description I need help implementing a reliable Firebase Authentication token refresh system for my web application. My app currently uses: frontend Firebase Authentication Firebase Cloud Functions (Node.js) API calls from Bubble to Cloud Functions Authentication handled through a third-party Firebase plugin in Bubble The issue I’m facing is ensuring that Firebase ID tokens refresh properly so authenticated API calls to my Cloud Functions continue to work after the initial token expires. What I Need Implement a secure refresh token flow Ensure ID tokens refresh automatically Allow my Bubble frontend to maintain authenticated sessions Ensure API calls to Firebase Cloud Functions remain authorized ...

I am building a full-featured, PIPEDA/PHIPA-compliant telehealth platform focused on real-time patient consultations. The core functions are already mapped out: secure video calling, automated clinical-note summaries with audit trails, integrated e-prescribing, and role-based dashboards for patients, doctors, and admin/support staff. . Key tech I expect to see (or strong equivalents): React or Vue for the front end, Node.js or Django for the back end, WebRTC for calls, and a FHIR-compatible data layer. CI/CD is already configured in GitHub; you just hook your pipelines into it. On acceptance we will agree on milestone cuts covering: 1) role-based auth and encrypted storage, 2) video consult module, 3) e-script flow, 4) summary audit engine, 5) dashboards and final compliance review. Each...

I maintain several large, structured datasets spread across MySQL, PostgreSQL and SQL Server instances. Only portions of the existing schemas are documented, so the very first step will be to inspect each system, reverse-engineer any missing metadata and confirm table relationships. Once the landscape is clear I need all records extracted, cleaned, normalised and deduplicated, then merged into a single, well-organised MongoDB database. Your work should include a carefully planned document model that supports growth, fast look-ups and straightforward analytics. Proper indexing, sharding strategy (where appropriate) and query optimisation are critical because future workloads will be heavy and latency-sensitive. Please deliver: • An optimised MongoDB schema and architecture diag...

We are building a high-accuracy OCR system that extracts structured data from scanned documents and images such as invoices, receipts, ID cards, and application forms. This is not just text recognition — the goal is to build a reliable pipeline that converts messy, real-world documents into clean, validated, structured JSON data ready for databases or ERP systems. -Objective Develop an intelligent OCR engine that: Extracts text from scanned PDFs and images (JPG, PNG) Detects document type automatically (invoice, ID card, form, etc.) Identifies key-value pairs (e.g., Name, Date, Total Amount, Invoice No) Handles noisy images (low resolution, skewed, shadows) Returns structured JSON output Achieves high accuracy (≥95% on test dataset) -Technical Scope - Image Preprocessin...

I have a completed Node.js backend API sitting on my local machine that now needs to live on a server. I’m looking for someone who can: • Upload the existing codebase, install its dependencies, and configure the runtime environment (Node, npm, any required process manager like PM2). • Spin up a fresh MySQL instance, build the database structure I’ll provide (tables, indexes, sample data), and make sure the API connects cleanly via the current configuration file. • Run a quick round of endpoint tests with me to confirm data is flowing and responses match the expected JSON. No authentication layer is required right now, so you can ignore JWT, OAuth, or similar modules. If you prefer Docker, CI/CD pipelines, or Sequelize/TypeORM migrations, feel free to prop...
