Summary
👤
Senior🎓
Top SchoolBranislav Katreniak is a Lead Software Developer with 12 years of experience designing and delivering robust distributed systems, from embedded audio stacks to cloud backend services. He blends an architect’s mindset with hands-on implementation, driving multi-cluster deployments, major performance improvements, and root-cause analyses in production at Cisco. His background in algorithms, complexity theory, and distributed algorithms underpins work on real-time, networked audio systems and constrained ARM devices where he engineered heapless C++ solutions and master-election protocols. An active contributor to the Cap’n Proto project, he implemented JSON decoding into its C++ core, showing attention to interoperable, high-performance serialization. Based in Bratislava, he’s comfortable leading small teams, reviewing the majority of PRs, and translating rigorous academic training (PhD-level theoretical informatics) into pragmatic product features. He favors making the pieces fit correctly—often finding and fixing subtle platform bugs that others miss.
