Fullstack developer (React / Next.js / Symfony) with 6 years of experience.
I help companies build and evolve reliable, performant, and maintainable web applications.
I specialize in:
- Modern frontend development (React / Next.js)
- API creation and refactoring (Symfony / NestJS)
- Performance and architecture improvements
I also work with artificial intelligence tools and APIs to:
- Automate certain tasks
- Enrich existing products
- Explore new product use cases
All projects I work on are developed with particular attention to:
- Performance (frontend/backend optimization, queries, response times)
- Security (access management, data validation, best practices)
I enjoy experimenting and integrating pragmatic solutions.
Stack:
React, Next.js, TypeScript, Symfony, Node.js, PostgreSQL / MySQL / SQL Server, Docker
👉 Comfortable with both build and refactoring missions, with an efficiency and robustness-oriented approach.
