I will develop a full stack web app with react node and postgresql
Sebastien L.
About this gig
Need a web app that actually works in production not a throwaway prototype?
I build them. I'm a full-stack developer with a strong background in IT infrastructure. I design and ship custom web applications using React, TypeScript, NestJS and PostgreSQL, with a focus on clean code, security and reliable deployment.
WHAT YOU GET:
- Custom React front-end (responsive, modern UI)
- Secure backend API (Node.js / NestJS)
- Database design (PostgreSQL)
- User authentication & role-based access
- Dashboards, admin panels, forms, data tables
- Dockerized, production-ready deployment
WHY ME:
Most "AI-built" apps look good in a demo and break in production.
I deliver deployable, maintainable, documented systems built with real engineering practices proper auth, secure architecture, and clean handover.
Whether you need an internal tool, a SaaS MVP or a business dashboard, I'll build something solid you can actually run and grow.
Message me before ordering so we can scope your project and pick the right package. Let's build something that lasts.

Full-stack developer with a background in IT infrastructure (MSP). I design and ship custom web apps, mobile apps and websites — leveraging AI tools to deliver clean, secure, production-ready code fast. Not throwaway prototypes: deployable, maintainable, documented work you can actually run.
I’ve built and deployed real projects end-to-end, from database architecture to hosting and security. If you need something that works in production — not just a demo — let’s talk.
FAQ
Do you use AI to build the apps?
Yes, I use AI tools to speed up development — the same way a developer uses any modern tool. But every project is custom-built, reviewed, tested and engineered by me for security and reliability. You get real, production-grade code, not raw AI output.
Which technologies do you work with?
Front-end: React, TypeScript, Vite. Back-end: NestJS / Node.js. Database: PostgreSQL. I also handle authentication (OAuth/OIDC), Docker deployment and hosting setup.
Will I own the code?
Absolutely. You get full ownership of all source code, plus documentation so you (or another developer) can maintain and extend it.
Can you deploy and host the app for me?
Yes. Hosting setup is included in the Premium package and available as an extra on others. I can deploy to your server or a cloud provider of your choice.
What do you need from me to get started?
A clear description of what you want the app to do, any design preferences or examples, and the content/data it should handle. The more detail you share, the faster and better the result.
