    I’m building a new e-commerce website and the first milestone is a smooth, reliable shopping-cart experience. I need a full-stack developer who can take the project from a blank repo to a live site: setting up the front end, wiring it to a secure back end, connecting the cart logic, and deploying everything on a hosting platform of your choice.

Payment gateway integration and user accounts will come in a later sprint, so keep the architecture flexible enough to bolt those on without rewrites. Deliverable: • A responsive e-commerce site with functional shopping cart, pushed to a Git repository and deploy...

    I’m lining up experienced full-stack engineers for new roles with our U.S. partners—including teams at Meta, Apple, and Calendly—and I’d like to review your profile.

    I’m kicking off a green-field web application for D Daya AI and need a full-stack partner who can take the idea from wireframe to deployable product. The build starts from scratch, so you’ll own both the front-end experience and the back-end logic. Core requirements • Robust user authentication that covers sign-up, login, password reset, and role-based access. • Clean, interactive data-visualisation dashboards that make our AI outputs easy to explore and filter in real time. You’re free to propose the stack that best fits those goals—React, Vue, Angular on the front, Node, Django, or another performant back-end are all welcome as long as the final codebase is modular, well-documented, and easy for an internal team to maintain.

    I need a streamlined, cloud-based inventory management system that gives me an up-to-the-second view of stock across all locations. The core of the build is real-time inventory tracking tied to automated reorder alerts so that low-stock items trigger a purchase order or notification immediately. Flexible threshold settings and simple user permission controls must be baked in from the start. A clean, browser-based interface is preferred, but I’m open to a lightweight desktop or hybrid approach if it keeps performance snappy. Although barcode scanning is not a priority for the first release, I’d like the architecture to leave room to plug that in later without a major rewrite. Deliverables • Fully functional inventory application (front end + back end) with real-time stock...

    I’m looking for a skilled software developer who can take an e-commerce idea from concept to a production-ready web application. The core deliverable is a full-stack solution: a responsive storefront for shoppers, a secure checkout flow, and an intuitive admin area where I can manage products, orders, users, and basic analytics. While I’m open to the specific tech stack, I do expect clean, well-documented code, modern UI practices, and deployment guidance to a cloud host of your choice. Payment gateway integration, user authentication, and GDPR-compliant data handling are must-haves. The finished application should be easy for me to extend in the future, so clear architecture and concise documentation will be part of the acceptance criteria. If you’ve launched e-commerc...
