About Roch

Back-end developer specialized in **Java / Spring Boot**, I have about 9 years of experience (including 6 years full-time) mainly in the banking sector. I work on projects where code quality and system robustness are essential: refactoring of critical applications, securing flows, performance, and maintainability.

I have a strong sensitivity to quality topics. I rely on practices from Lean Software Development (0-bug approach, simplicity, pull flow...) which I have successfully implemented in several demanding contexts. My goal is always to deliver clean, tested, maintainable code — and to avoid the accumulation of technical debt.

I also have experience as a Tech Lead, but I prefer today to focus on a lead dev or technical referent role, more focused on execution than management. I am autonomous, comfortable challenging an architecture, supporting a team, or taking on a complex project.

I work primarily in Java / Spring Boot, but I am also comfortable with front-end topics (React, Angular) or CI/CD when needed. I can work on full-stack projects, or help streamline the delivery chain.
