Rockstar🎓
Top SchoolBohdan Storozhuk is a Senior Software Engineer based in the UK with 11 years of experience designing and operating resilient, high-performance distributed systems. He has driven architectural redesigns, performance optimizations and CI/CD transformations that cut release cycles from weeks to days, and currently applies that expertise at Spotify. A pragmatic engineer with deep Java and systems skills, he’s contributed core rate-limiting features to notable open-source projects like resilience4j and performance-focused improvements to uber-go/ratelimit and dropwizard/metrics. He brings hands-on incident management and large-scale integration experience (40+ third-party APIs) and a track record of converting flaky, 24/7-supported systems into robust, observable platforms. Notably, his background in physical and biomedical electronics underpins a strong analytical approach to low-level performance and concurrency challenges.
