01 / About

Built for the parts users never see.

I design and own scalable distributed systems end-to-end: API design, data pipelines, DevOps, observability and production deployments.

Recently: a DigitalOcean → AWS migration with Control Tower, SSO and Terraform; a FastAPI screening service rebuilt to run 3–5× faster; and a Go scraping gateway sustaining thousands of concurrent outbound requests with provider failover.

bias: performance / reliability / infra worth being on-call for
