What I concretely bring:

Robust and scalable backend (Java / Spring Boot, hexagonal architecture, microservices)

Performant and maintainable APIs (clean code, SOLID, DDD)

Modern and fluid frontend (Angular, React, VueJs, TypeScript)

High quality standards: unit, integration, E2E, mutation testing

Ability to intervene in critical contexts (production, high volume)

My specialties:

Java / Spring Boot (API, microservices)

Angular (complex applications)

Architecture & performance

Demanding environments (banking, e-commerce, hospitality)

I integrate quickly into teams and am proactive in technical choices and continuous improvement.
