I’m expanding a JavaScript-driven web platform that runs Node.js on the back-end and React on the front-end. The project needs a seasoned full-stack developer who can design new features end-to-end, refine the existing architecture, and keep our CI/CD pipeline smooth. Mastery of modern JavaScript, Node.js, Express, REST or GraphQL patterns, and state management in React is critical. Familiarity with TypeScript, MongoDB, or PostgreSQL will make collaboration even easier, though it isn’t mandatory. An intern will join at the same time, and I expect routine tasks to double as learning opportunities. The intern’s focus will be: • Assisting with coding • Testing and debugging • Documentation Your first milestone is to ship a self-contained feature and me...

I have the core LocalFix platform running on the MERN stack; what I still need is the role-specific layer that lets real users start transacting. For this phase I only care about two roles—Customer and Service Provider—and about giving each of them just the abilities checked below. Everything else (search, category browsing, admin dashboard, etc.) already lives in the codebase. Deliverables I need from you • Customer role – Auth protected area where a logged-in customer can submit a booking request for any service listing. • Service Provider role – Editable profile page (bio, skills, pricing, availability). – Booking inbox showing pending requests with Accept / Decline actions that update status in MongoDB and trigger email or in-...
I want to launch an e-commerce site built on WordPress that sells only digital products. After checkout, customers must receive an automatic, secure download link—no physical shipping steps at any point. WooCommerce (or another proven digital-commerce plugin) should power the cart, payment gateway connections, and licence or file-access rules. Design-wise, the theme needs to feel clean and creative, with space for eye-catching screenshots and concise product copy. Think fast-loading pages, intuitive navigation, and a fully responsive layout so buyers on mobile can purchase and download just as easily as desktop users. Core set-up tasks include: • Installing and configuring WordPress and the chosen e-commerce plugin for “Downloadable products” • Connecting...
My AI-driven trading assistant is already handling strategy logic and order routing; the missing piece is a solid, low-latency real-time data feed. I want you to wire the assistant to Alpaca’s streaming API so I can consume live trade updates reliably in Python. Scope • Integrate Alpaca API’s websocket stream and surface Real-time trade updates in a clean, testable Python module. • Feed must plug into my existing Node.js/React dashboard through a lightweight REST or WebSocket bridge so the UI refreshes instantly when new ticks arrive. • Connection management, reconnection logic, and basic error handling are part of the job. Keep the code readable and document the key functions so I can extend it later to current-price or historical endpoints if needed. Ac...

I am ready to kick-off the build of a production-ready e-commerce web application and I’m looking for a developer who can take it from architecture through deployment. The core of the project is a full-stack solution—MongoDB, Express, React, and Node.js are my preferred tools, though I’m open to pragmatic use of SQL where it improves performance or reporting.
