Summary
🤩
Rockstar🎓
Top SchoolRoger Peppe is a founding engineer with 16 years of software engineering experience, currently building developer tooling and language infrastructure at CUE Labs. He has a strong Go systems and backend focus, evidenced by sustained contributions to prominent projects including the Go toolchain, encoding/xml, go-yaml, and the CUE language itself. His work blends practical tooling (module and archive utilities, rate limiting, symbol definition tools) with careful attention to correctness and testing—adding coverage, benchmarks, and fixes that keep core libraries robust across Go versions. Prior roles at InfluxData, Heetch and Canonical reflect breadth across cloud, orchestration and data systems, while an early academic research background informs a methodical, low-level problem-solving style. Based in rural Northumberland, he combines deep open-source craftsmanship with the product-minded perspective of a startup founding engineer.
