I build backends
that hold the line.
Senior Go Engineer • Distributed Systems • Backend, Infrastructure & Developer Tooling
13+ years delivering production systems — 8+ of them in Go. I build high-throughput distributed systems (gRPC, GraphQL), developer tooling people actually enjoy using, and security platform integrations — with a record of 10–40x performance gains rebuilding systems from first principles. I ship open source under the Tecnologer name.
