About Junior

Mobile developer from 42 and immersed in the Flutter ecosystem since its beta versions (v0.8), I now help companies create high-performing, robust, and scalable mobile applications.

🛠 Development Side (The Builder):
With experience as a founder (Lead Dev on over 20 client projects), I master the entire application lifecycle: from technical design (offline-first architecture, API, database) to deployment on the stores and CI/CD automation. My obsession: clean code (SOLID principles), tested, and maintainable.

🎓 Training Side (The Mentor):
Former Educational Manager (Rocket School, ESD), I have a passion for knowledge transfer. I audit your projects, structure your best practices (Code Review, Linters), and upskill your junior/intermediate developers to make them autonomous.

Whether you need to develop a complex feature (geolocation, data synchronization, monetization) or coach your tech team, I adapt to your challenges with the rigor and pragmatism acquired at 42.
