Senior🎓
Top SchoolMikhail Puzanov is a Specialist Software Engineer based in Amsterdam with over a decade of industrial experience building high-performance back-end systems, databases, and distributed infrastructure. He brings deep expertise in Java and Scala ecosystems, proven by years working on application containers, concurrency, profiling, and RPKI tooling at RIPE NCC, plus meaningful contributions to open-source projects such as improving DNS resolution and happy-eyeballs behavior in the widely used http-client Haskell library. Comfortable across paradigms, he also applies functional programming and strong Haskell experience to real-world problems, and has substantial hands-on knowledge of PostgreSQL/Oracle/MySQL performance tuning and replication. His background includes low-level C/C++ and parallel computing from academic work, which informs his pragmatic approach to profiling, memory and CPU optimization, and concurrent system design. Notably, he blends production-grade engineering with community-driven open-source improvements, demonstrating both operational rigor and curiosity-driven craftsmanship.
