Summary
🤩
Rockstar🎓
Top SchoolBryn Cooke is a Principal Engineer with 15 years of experience building distributed systems, graph databases and high-performance back-end infrastructure, currently driving core routing and federation work at Apollo GraphQL. He brings deep Rust and Java expertise alongside practical knowledge of Tokio, GraphQL, TinkerPop and Cassandra, and has repeatedly improved core graph frameworks like Apache TinkerPop and Titan. Bryn has combined hands-on engineering with technical leadership at DataStax—shaping graph and storage-index teams—and brief tenures at Booking.com and earlier startups. An active open-source contributor, his work on TinkerPop and the Apollo Router shows a pattern of fixing subtle compatibility and traversal issues and adding planner/caching primitives. Based in North Norfolk, he pairs systems-level thinking with a curiosity for spatial data and UUID/GeoJSON handling that underpins his database work. Collected over a long career, his strengths are pragmatic architecture, low-level problem solving in Rust/Java, and improving interoperability across graph implementations.
