Alex Robinson is a Senior Principal Systems Engineer with 12 years building robust, large-scale distributed systems across Cloudflare, Cockroach Labs, and Google. He designs and ships edge storage and coordination systems for serverless platforms—working on Workers KV, Durable Objects, R2, and Cloudflare Queues—while previously driving core internals and performance optimizations in CockroachDB and early Kubernetes/GKE. A pragmatic problem-solver, he has deep experience reducing CPU and concurrency issues in production (e.g., gossip optimizations and Cap’n Proto improvements) and improving cloud provider integrations for scale. He combines hands-on systems programming with technical writing and customer-facing mentorship, evidenced by documentation work and operator-facing tooling. Based in Austin, he brings a rare blend of low-level performance tuning and distributed system architecture applied across high‑traffic, global networks.
