Back to original languageAbout Louis
Backend Java Spring Developer with over 7 years of experience, including 4 years as a Technical Lead on multi‑application maintenance projects. I operate autonomously on complex backend topics and can also troubleshoot issues across the entire stack (including frontend).
I help teams design, optimize and enhance high‑performance backend systems: architecture, development, refactoring, version upgrades, security, and performance improvements.
Clients value my strong autonomy and my ability to deliver clean, reliable work quickly: clear communication, clean code, best practices, and comfort handling critical production issues are key aspects of my work.
Looking forward to discussing how I can support your project.
