Backend engineer. Mostly Go, mostly distributed systems.
Currently at C6 Bank, building high-throughput event-driven services with spec-first APIs, MongoDB data layers, NATS-routed event pipelines. Previously at Dell Technologies, where I built an in-house Go pub/sub system from scratch because corporate IT lead times made Kafka impractical.
I care about spec-first APIs, codegen where it pays off, simple architecture, and systems that don't bother me in my sleep.
Open to Go contractor roles. Remote.
