About Léo

Fullstack Engineer – Web & Mobile Applications · Next.js / React / NestJS · Autonomous delivery

I design and develop complete web applications, from front-end to API, for startups and SMEs that need an autonomous developer capable of taking a project from end to end.

My main stack: React / Next.js on the front end, NestJS / Node.js on the back end, TypeScript everywhere.

What sets me apart: I've coordinated technical teams in addition to coding — I understand product constraints, I know how to prioritize, and I deliver without needing to be supervised.

What I can do for you:
- Create a web or mobile application from scratch
- Take over and evolve an existing project
- Implement tests (unit, E2E) to make your code reliable
- Integrate a CMS, optimize SEO, connect third-party APIs
