Summary

Rockstar🎓
Top SchoolMarcin Skalski is a Senior Software Engineer based in Krakow with 11 years of experience designing and operating large-scale cloud-native infrastructure and service mesh platforms. He currently builds core control-plane features for Kuma, a CNCF Sandbox multi-zone service mesh backed by Envoy, and has a strong focus on networking, policy management and runtime performance. Previously he led the Service Mesh and Cloud Platform team at Allegro, rebuilding the team from scratch to manage >1500 services and ~2M RPS while improving deployment flows, observability and developer tooling. Marcin combines hands-on backend engineering (Kotlin, Go, Envoy, Consul) with on-call incident leadership and platform-level performance tuning that measurably reduced latency and incidents. He’s an accomplished open-source contributor and public speaker who also runs hiring and systems-design workshops, reflecting a mix of technical depth and people leadership. An understated strength is his knack for building developer-facing tools (like service maps and SDK optimizations) that simplify large, complex ecosystems.
