Description

Full-Stack Developer with 4 years of experience specializing in building scalable, high-performance web applications.

My technical approach is fully up-to-date to deliver robust solutions by combining Java 21 (Spring Boot) on the back-end and Angular 21 (Signals and Standalone Components) on the front-end.

I help product companies and technical teams accelerate their development, migrate legacy architectures, or build new platforms from scratch with clean code and unit tests.

I have autonomously managed the complete development cycle of efficient REST APIs, microservices architectures, and modern, user-optimized administration dashboards.

I offer total autonomy from day one, proactivity, and flexibility to integrate into results-oriented agile teams.

Immediately available for remote freelance projects or hybrid collaborations.
