Summary
🤩
Rockstar🎓
Top SchoolAndriy Zavada is a seasoned software engineer with 13 years of experience, specializing in backend systems and a long-standing passion for Erlang/OTP. He contributed to core distributed systems work at Basho (notably improving Riak KV/TS code quality and APIs) and has a track record of pragmatic refactoring, type-safety improvements and build tooling enhancements. Andriy has worked across industries from HPC and HFT to chat platforms, often preferring to deepen expertise in a single reliable language rather than chasing trends. A former neuroscientist with a PhD, he brings rigorous, research-minded problem solving to production engineering. He also has a quirky roots-in-logic side: he wrote a functional Prolog interpreter in 1995 and still enjoys the consequences of that experiment. Based in Ukraine, he’s focused on producing robust, maintainable systems and quietly keeping legacy codebases healthy.
