I’m launching an e-commerce site that, for now, serves purely as a browsable product catalog. I need someone who can turn my Figma wireframes into a fully responsive, production-ready front end built with HTML5, CSS3, Bootstrap 5 and either React (preferred) or Angular—use whichever framework lets you move fastest while keeping the codebase clean and component-driven. Scope • Build the core layout: homepage, category views, product listing grid, and detailed product pages. • Implement client-side routing, search, and category filtering so users can explore the catalog smoothly without page reloads. • Ensure every screen scales gracefully from mobile to desktop, following the Bootstrap grid and flex utilities. • Hook in dummy JSON or a simple REST en...

I need a single code-base solution that lets me run free-fire style tournaments seamlessly on iOS, Android, and the Web. The core flow is simple: players (or full teams) create an account with email + password, register for an event, get auto-placed into the match schedule, and then I can record or update scores so standings update in real time. My ideal build keeps the interface clean for mobile while still giving me a full dashboard online, so frameworks such as Flutter, React Native or even a well-structured PWA backed by Node/Firebase are all fine as long as you can ship a responsive experience across those three platforms. Deliverables • Production-ready apps for iOS, Android, and a responsive web portal • Secure email/password authentication set up end-to-end (sign-up, ...

I’ve already shipped the core UI for a couple of productivity-focused apps built with Claude-React and backed by Firebase. What’s still missing are the key Firebase services that turn them from prototypes into production-ready tools. Here’s what I need you to wire up inside the existing codebase: • Authentication system – please use Firebase Authentication, creating a clean sign-up / login flow. Two roles matter: Admin and Regular User. The role should be stored securely and exposed to the app through context so I can gate features later. • Real-time database updates – connect the current data layer to Firestore (or the Realtime Database if you prefer) so edits, additions, and deletions propagate instantly across all clients. Offline persistence a...

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.

TransitPro already handles schedules, seat availability, online booking and basic back-office tasks, but its look, speed and feature-set now need a serious lift. I want the whole system to feel modern on desktop and mobile, run faster, and, most importantly, offer live bus information. Top priority feature – Real-time tracking Please build a tracking module that gives passengers and staff: • Bus location updates in real time • Accurate estimated arrival times • Instant notifications when delays or route changes occur Beyond tracking, the job includes: refreshing the UI/UX, squashing lingering bugs, tightening performance, integrating a secure online payment gateway, and sharpening the existing admin dashboard. The stack is React, Node.js/Express and MongoDB,...

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’m setting up a dedicated platform that streamlines end-to-end supply chain operations—everything from order intake to final delivery—so I need a developer who can own the entire build of both the back-end software and its companion mobile app. Core objectives • Design a central dashboard that gives real-time visibility into inventory, purchase orders, and carrier status. • Develop native apps (iOS and Android) for on-floor staff to scan, update, and confirm movements on the go. • Implement role-based access, automated alerts, and API hooks so the system can sync with existing ERPs and carrier systems. Tech preferences I’m flexible on stack, but experience with cloud-first architecture (AWS or GCP), microservices, React/Angular for web,...

I need a web-based dashboard that lets me monitor core business analytics at a glance. The focus is on clear, responsive charts and graphs that track two critical metrics: sales performance and website traffic. The data will come from sources I can expose through REST APIs or flat files, so the build should accommodate both. I’m open to the charting library you prefer—whether that’s D3.js, , Highcharts, or another modern JavaScript option—so long as the visuals load quickly and can be filtered by date range, product line, and traffic channel without page refreshes. Please structure the project so future datasets can be plugged in with minimal code changes. A lightweight admin panel or straightforward config file approach is fine; I just don’t want to wad...

I’m building a central API that receives every new order from my Wix storefront, checks real-time stock across three nearby locations, compares both availability and price, then decides which store should fulfill the sale. Once the choice is made, the same service must decrement inventory at that location and raise an instant alert whenever stock dips below a threshold or sales spike unusually. Because I have no existing back-end, the whole pipeline—orders, inventory, pricing, and alerts—needs to be created from the ground up. Orders integration is my top priority, so the initial milestone should prove that an order placed on Wix can travel through the API, retrieve inventory data, and respond with a recommended store. I’m open to your suggested stack: Node.js wit...

I dont have have my page layouts sketched in Figma; need to design figma and then I need the whole site taken from design to a live, fully-functioning business website.

At hand-off I expect: • Source code with clear README • Environment variables documented • Deployed production link plus credentials for a...

I’m looking for an experienced full-stack software engineer who can take ownership of a new business platform from architecture through launch. The core product will be a full-stack solution, centred on a web application, but I’m flexible on the exact tech mix—React, Angular, or Vue.js on the front end and Node.js, Django, or Ruby on Rails on the back end all remain open for discussion. Your insight will help us pick the stack that best fits our growth plans and team skills. Here’s what I need from you: • Translate high-level business requirements into a clean, scalable architecture. • Build out the front-end UI and back-end APIs, ensuring tight integration and responsive performance. • Set up CI/CD, automated testing, and basic cloud deployment ...

I’m building a green-field product that needs a solid foundation across web, mobile and cloud. The server side will run on .NET (Core/Framework) and expose RESTful endpoints organised as micro-services. For the browser I’m happy with either Angular or React—pick whichever you are fastest with—and the companion mobile app will be written in React Native so we can share as much logic and styling as possible. The data layer can land on SQL Server, a NoSQL store or a mix of both; I’m open to your recommendation as long as the choice is justified and future-proof. Everything will be hosted on AWS or Azure, wired into a CI/CD pipeline (GitHub Actions or Azure DevOps are fine) so every commit ships automatically through test, staging and production. Clean code, SOLI...

I’m hiring a seasoned .NET + Angular engineer who can act as a personal mentor for a friend of mine in Udaipur. She has three years of support experience in infosys and has just moved into an SDE role in different company, so she needs guided, practical coaching rather than generic tutorials. The focus is pure mentorship and guidance delivered through one-on-one video calls. During these sessions you will walk her through the tickets already assigned to her, explain the underlying concepts, review her code, and show her how to debug, refactor, write tests, and follow best practices that align with real-world enterprise workflows.
