🧠 About
I am a full-stack React Native / TypeScript developer specializing in building cross-platform SaaS applications, from the first line of code to production deployment.
With 4 years of startup experience, including 2 years in technical management and 1 year in Product Management, I act as a Full-Stack Builder to design, build, and rapidly deliver complete products, while ensuring a clean and sustainable architecture.
My approach: deliver a functional, maintainable, and scalable product, without compromising on quality.

- Creation of complete MVPs: design → code → deployment
- Technical architecture & backend integration
- Performance and user experience optimization
- Production deployment
I can join an existing project or start from scratch, with a focus on execution speed, code quality, and ease of use.
