I’m building an end-to-end website for SRPP Polytechnic Institute and want it written entirely with Node.js, Express, MongoDB, and EJS templating. The scope is straightforward but complete: The core of the site is an open-access student portal paired with a course-management section. Because I don’t need user authentication at this stage, every visitor should land straight into the content without being asked to log in or create an account. The course area simply needs to present detailed college information for each programme—title, overview, syllabus highlights, credits, faculty contacts, and any downloadable PDFs—while allowing me to add, edit, or retire courses from an admin back-office. Although the event calendar is not a must-have right now, please architec...

I need a senior-level full-stack developer who can dive straight into my existing WordPress theme, decode its current template files, and build three focused enhancements: • Add-to-Cart Menu – purely an appearance overhaul. The layout and overall design need to be re-worked so the button, mini-cart, and surrounding elements sit cleanly within the header without breaking responsiveness. (If you think subtle colour or typography tweaks would improve consistency, I’m open, but structure comes first.) • Menu Bar Categories – restructure the category bar so it reflects my latest product hierarchy, loads quickly, and inherits the theme’s hover effects. No new plugin; keep it native to the theme’s PHP/JS stack. • Sales Price Indicator – inject...

I need a clean, reliable API bridge that keeps booking details flowing instantly between Djubo PMS and Lovable in both directions. Whenever a reservation is created, modified, or cancelled in either system, the other side must receive and store the update in real-time without manual intervention. Both platforms already expose RESTful endpoints and keys; what I’m missing is the middleware logic that watches the webhooks, maps the fields, handles authentication, and writes robust error handling and retry routines so no transaction is lost. Deliverables • Node.js (or similar) service with clear, well-commented code • Field-mapping document showing how each Djubo attribute pairs with its Lovable counterpart • Deployment guide for a Linux server (Docker preferre...

I have a steady flow of web projects that require a seasoned hand in JavaScript and Node.js. You will jump straight into feature building, refactoring legacy code, and occasionally lending architectural advice, so proven senior-level experience is essential. Because most of my stakeholders speak French while our documentation is in English, you must be comfortable switching between the two languages during calls, chats, and code reviews. All work is billed at US $3 per hour. I log and approve time daily, so reliability and clean, well-commented commits are critical. If you’re ready for consistent hours, clear objectives, and a straightforward pay structure, let’s talk.

Automatic calculation of tax liabilities, deductions, late-fee computations, and real-time validation against government schemas should run in the background so the user only sees a smooth progress bar. ...

I have a web application-company website in active development and now need a developer who feels at home in React while still understanding the wider full-stack picture. The immediate focus is on polishing and extending the front-end: building new components, tightening up state management, and wiring everything cleanly to Firebase (Firestore, Auth, Functions, Hosting). I work iteratively: small, well-defined tasks that roll into weekly pushes to production, so clear communication and clean Git commits matter to me. When you reply, show me concrete past work that proves you have already shipped React projects backed by Firebase. GitHub links or live demos that highlight responsive UI, sensible folder structure, and secure data handling will help me move quickly to hire. If you thriv...

I need a full-stack developer who has already built tools that capture live streams and turn them into downloadable files. The goal is a windows/mac app that lets a user paste a link, choose a time window, and then receive an MP4 file once the recording is finished. Core scope • Capture live or upcoming streams from various websites—must work flawlessly. If your code can be structured so other HLS sources could be added later, even better. • Offer both Scheduled and Monitored recording modes. Scheduled means the user sets a start/stop time; Monitored means the app watches the channel and begins automatically the moment the stream goes live, ending when it finishes. • Deliver recordings in MP4. Internally you’ll likely deal with HLS or TS segments, so you s...

I am embarking on a green-field build of an end-to-end business platform and I need an experienced full-stack partner who has taken similar products from concept right through to launch. Scope The core of the project is a web application that must run smoothly on desktop, mobile, and tablet browsers. Native iOS and Android apps will follow, powered by the same back-end. Alongside standard account, billing, and workflow modules, three integrations sit at the heart of the build: 1.

AI-driven document automation – the system should draft proposals, letters, and other routine paperwork, plus gather reference information from both publ...

The project will be crafted from scratch and must feel as refined as any top-tier SaaS product. A clean Material Design aesthetic guides every screen, so visual polish goes hand-in-hand with smooth interactions.

My enterprise platform is already running on ReactJS in the front-end and Spring Boot in the back-end, yet the programming side of our internal operations still feels heavier than it should. I want to streamline the way new features move from idea to production, tighten the feedback loop between UI and APIs, and remove the little friction points that slow the team down today. You will work across the full stack: shaping clean React components, hardening Spring Boot services, refining our PostgreSQL queries, and wiring everything together with well-structured REST endpoints. Expect to touch build pipelines (Maven, Webpack), unit and integration tests, containerisation (Docker), and CI/CD scripts while you’re here—anything that helps us ship faster and with fewer surprises.
