Summary
👤
Senior🎓
Top SchoolJoaquín Serna is a Senior Security Engineer with a decade of experience designing and hardening backend architectures across cloud environments. He combines low-level systems expertise—writing kernel-level eBPF components in C—with high-level service design in Java, Go and C#, enabling observability and performance tuning at scale. At Bewise he led architectural refactors and ownership of system-wide decisions, and now applies that operational security focus at Mercado Libre. Comfortable across the product lifecycle, he moves from early feature design to deployment and CI/CD automation while collaborating closely with cross-functional teams. Based in Vicente López, Buenos Aires, he pairs academic grounding from the University of Buenos Aires with practical, production-first engineering instincts. Notably, his blend of kernel-space tooling and distributed backend work gives him a rare lens for both performance and security trade-offs.
