Hi, I'm Victor Leveneur 👋
Cybersecurity Engineer & Full-Stack Developer
I build secure, scalable applications with clean architecture and production-grade engineering. Former Tech Lead specializing in backend development, DevOps, and security hardening.
About Me
I'm a Cybersecurity Engineer with a Master's degree from Université de Grenoble-Alpes and 4+ years of experience building secure, scalable applications. As a former Tech Lead & DevOps at Black Pearl, I led technical teams, architected production systems, and implemented security-first engineering practices.
My expertise spans full-stack development, cloud infrastructure, and security hardening. I'm passionate about clean architecture, automated testing, and building systems that scale.
When I'm not writing code, I'm exploring new tools and staying ahead of the latest in cybersecurity and software engineering.
