Summary
🤩
Rockstar🎓
Top SchoolMichal Matczuk is a seasoned software engineer with 11 years building high-performance distributed systems and data infrastructure that stay up under real load. He has designed and shipped production HTTP/2-based networking stacks and reverse proxies handling multi-terabyte daily traffic, achieving order-of-magnitude throughput gains through protocol and Go implementation improvements. At ScyllaDB he created gocqlx (a widely adopted CQL query builder, ORM and migration tool) and led work on a lock-free Go driver that outperformed competing drivers in large-scale benchmarks. His open-source contributions span rclone performance optimizations and a notable go-http-tunnel project (an HTTP/2 ngrok-like tool) that gained community recognition. Comfortable both leading teams and diving into low-level performance tuning, he also contributes fixes to the Go standard library and mentors engineers on resilient networking and storage software. Based in Poland, he brings a pragmatic, results-driven approach to making byte-copying and distributed I/O fast and reliable.
