Experience
Go Systems & Open Source Contributor
CNCF (Cloud Native Computing Foundation) & Independent 2026 - 2026
Authored upstream Go contributions across CNCF projects: fixed GPU cost metric parsing in OpenCost (#4133), built runtime metric test suites in Jaeger Tracing (#9956), and expanded label matcher coverage in Prometheus (#20256). Engineered PortPulse: a cloud-native API gateway with a 32-shard lock-striped rate limiter (benchmarked at ~7.95M ops/s) and gRPC tracing pipelines. Built GoBalance: a zero-allocation Layer-4 TCP reverse proxy utilizing sync.Pool (26 ns/op, 0 allocs/op) with active Prometheus health checks. Developed ByteCache: an in-memory key-value store with background TTL eviction running at 50M+ reads/sec under -race verification.
