Rockstar🎓
Top SchoolCyryl Płotnicki is a seasoned software engineer and engineering manager with 14 years’ experience building and leading teams that deliver large backend systems, now serving as Principal Engineer at NatWest Cushon. He’s a hands-on programmer at heart who has progressed from low-level systems and mobile games to heading core engineering at FORM3 and writing Rust-based open source tooling for IoT and WASM. Comfortable leading fully remote teams, he combines practical systems understanding with people leadership—running 1:1s, career coaching and technical mentorship. An open source advocate, he teaches Rust through pair programming and runs a free fuzzing service for OSS projects, funded via Liberapay. Outside work he’s a maker and electronics enthusiast who cycles and rock-climbs, reflecting a pragmatic, curious approach to complex problems. He deliberately avoids crypto/web3 and defense sectors, preferring roles aligned with his values.
