Senior🎓
Top SchoolJacek Złydach is a Principal Software Engineer with 15 years of experience building performance-critical industrial and cybersecurity systems, currently leading development of OPC UA-based data access clients and tooling at Siemens Digital Industries Software. A true polyglot, he has shipped production software in C++, Erlang, Java, and Common Lisp, and has a track record of creating high-performance simulation and probabilistic modeling systems as well as custom debugging and ETW-based observability tools. He mentors distributed teams, establishes testing and architecture best practices, and crafts developer tooling that measurably improves productivity. Outside of product work he helped run Hackerspace Kraków and teaches programming, reflecting a long-standing commitment to community and hands-on maker culture. An unusual strength is his ability to move rapidly from prototype to optimized production—demonstrated by order-of-magnitude performance wins and an open-sourced Common Lisp tracer born from real R&D needs.
