    Quiero implementar un asistente en WhatsApp que combine respuestas automáticas bien programadas con la intervención manual de un operador cuando sea necesario. Las respuestas automáticas deberán generarse de forma personalizada para cada cliente, no solo con mensajes genéricos, y centrarse sobre todo en gestionar pedidos y su seguimiento. Lo que necesito de tu parte: • Definir y configurar el flujo de conversaciones en la API de WhatsApp Business o en una plataforma equivalente (Manychat, Twilio, Wati, etc.). • Crear plantillas dinámicas que usen datos de cada pedido (número de orden, estado de envío, tiempo estimado) para que el mensaje se sienta único. • Diseñar alertas o hand-off claros para que el...

    I’m ready to launch an online store and need a WordPress specialist who can guide the entire process—from securing the right domain to handing over a fully functional shop. The site itself will be an e-commerce build on WordPress (most likely WooCommerce), and it must include payment gateway integration, a clean product catalog, and the ability for customers to leave reviews. Because I haven’t purchased a domain yet, I’ll look to you for advice on choosing an available name, completing the registration, and pointing the DNS to my hosting. Once the domain is active, I’d like the store designed, configured, and tested so that I can add or update products on my own after launch. Deliverables: • Help me choose and register the domain, then connect it to my ...

I would like it built on Square Online (that’s my current preference because it links directly to my POS), but I’m open to your advice if you can achieve smoother results elsewhere without losing the Square payment flow. Core features I must see live before launch: • Online ordering with real-time inventory sync and checkout via PayPal and Stripe • A mouth-watering photo gallery that I can update easily when new treats come out of the oven • Store locator, hours, and click-to-call/contact details displayed clearly on both desktop and mobile • Social media widgets embedded so customers can share photos ...

The goal is a native iOS and Android app that: • pulls every public-facing page and function from my current site, • plugs directly into Mighty Networks so community discussions, content sharing, messaging, and event reminders appear seamlessly, and • lets members purchase event tickets inside the app with the payment immediately reflected on the website roster. Core functions I must see inside the app: user profiles, full event scheduling (create, edit, RSVP), and secure payment processing (Stripe is already live on the site, but I’m open to your suggestion if another gateway will sync more cleanly with the app stores).

    Integrate PayPal V6 Checkout

    I have a small, custom-built JavaScript shopping cart that serves only digital downloads. At the moment it relies on a single PayPal “Pay Now” button; every product click jumps straight to payment. I’m ready to switch to PayPal’s newer V6 Checkout so customers can add several items, review a summary, and then pay—while still receiving instant download links on successful payment. The cart logic, product data, and fulfilment scripts are already in place; what’s missing is the payment layer.

    I already route checkout traffic for the Geidia payment gateway through an iframe-based IP proxy so the request appears to originate from my VPS’s static address. That lets the initial payment page load, but once the JavaScript-based redirects kick in for 3-DS and the final callback, the flow escapes the tunnel and the gateway never notifies my Laravel callback URL. I need a clean, fully isolated solution that: • keeps every redirect—including the 3-DS challenge—inside the proxy path • forces the gateway to see only the server’s fixed public IP, never the shopper’s browser IP • returns the gateway’s success or failure response to my Laravel controller without breaking session or CSRF tokens You’ll be free to choose the mo...

    I’m launching a new Shopify storefront dedicated to selling tangible, ship-to-customer products and I need someone who can take the build from blank canvas to ready-for-orders. The core of the job is setting up a clean, conversion-focused theme, organizing the product catalogue (with variants, SKUs and high-quality imagery), and configuring shipping, taxes and a secure checkout so customers can complete a purchase without friction. While my immediate priority is a streamlined store that can process payments and dispatch orders reliably, I’m open to adding extras such as product reviews or advanced inventory tools once the basics are humming—so if you have suggestions, let’s talk. Please ensure the site looks equally sharp on mobile, loads quickly and is handed over...

    I am completing my final-year web development project and need a polished portfolio site that also demonstrates core e-commerce functionality. The site’s primary role is to showcase my work, yet it must convincingly handle: • Payment gateway integration • Customer reviews section • Product search capability Clean, responsive design is essential because the grades hinge on both aesthetics and code quality. Please deliver well-commented source code, mobile-first styling, and a short README with setup steps so I can deploy it on the university server. Cross-browser compatibility and a Git repository for version tracking are required. I will sign off once the site installs smoothly, every listed feature works as described, and the interface feels professional on de...

    I need a single Android application that seamlessly blends three experiences: a full-featured shopping portal, a robust bill-payment hub, and a stored-value wallet. For the wallet, real money movement is essential. Users must be able to add funds straight from their bank accounts and through a payment-gateway top-up flow, see every credit or debit in a clear transaction history, and send money to other users instantly. The shopping side should feel like any modern e-commerce app: a browsable product catalog, an intuitive cart (with quantity edits and promo-code entry), and a wishlist that persists across sessions so shoppers can save items for later. When a user checks out, the wallet balance should appear as a payment option alongside any external gateways. Bill payments should f...

    I’m building a fresh, modern-looking website for a small tour company in Jamaica and need a developer who can take it from concept to launch. The visual direction is clear—clean lines, plenty of white space, and responsive layouts that look sharp on desktop and mobile alike. Two core functions must be in place from day one: • Secure online payment system (credit/debit cards; the exact gateway we can choose together). • A straightforward contact form that routes submissions to my email without fail. Beyond those essentials, I’ll count on you for: • Setting up a simple content management workflow so I can update text and images myself. • Basic on-page SEO best practices baked in. • Cross-browser testing to ensure everything works smoothly. ...

    I need a developer–marketer who can take an e-commerce project from blank page to first sale. The core assignment is to build a responsive WordPress (or comparable custom) site whose primary purpose is selling products online. It must include a seamless shopping cart, secure payment-gateway integration, and a product-review feature so customers can share feedback. Once the store is live, I want you to push traffic and conversions. That means on-page SEO, a practical lead-generation funnel, and paid as well as organic campaigns on Facebook and Instagram. If expanding to LinkedIn or other networks later makes sense, we can discuss, but for now those two platforms are the focus. Quality and speed both matter: I often work with tight launch dates and expect clean code, error-free copy,...

    I need a clean, user-friendly website that lets our customers browse upcoming treks and reserve their spots in just a few clicks. The core focus is end-to-end booking: displaying trek dates, taking customer details, accepting online payments, and immediately updating availability on the back end. If you have solid, demonstrable experience building similar reservation or e-commerce platforms and can move fast, I’d like to hear from you. The project is time-sensitive and I’m aiming for a full launch as soon as possible, so I value developers who can show they’ve hit tight deadlines before. Key deliverables: • Responsive front-end pages that showcase each trek’s itinerary, difficulty level, price, and gallery • Secure booking workflow with payment gatew...
