You will get a full-stack web app with React and Node or .NET
Project details
A fast, reliable web app built end to end — front end to back end. I design and build modern web applications with clean, scalable code, so you get one accountable developer from start to finish. Whether it's an MVP, an internal tool, a dashboard or a full product, I handle the whole stack.
You get a responsive, intuitive UI (React / Next.js), a solid backend and API (Node.js or .NET / C#), proper database design (PostgreSQL), authentication and business logic, and deployment so your app goes live. I follow Clean Architecture and SOLID principles and deliver documented code you fully own.
I've shipped booking platforms, e-commerce shops and business systems — you can see live demos in the gallery. Tell me what you're building and I'll scope it clearly before we start, with no surprises.
