a selection of things i've built over the last few years.

An on-site agent for this portfolio that answers questions about my work, writing and background. A custom LangGraph tool loop coordinates its tools; FastAPI streams each step, and an evaluation suite checks routing and answer quality. Postgres keeps conversations durable, while bounded retries and a warm-on-load health check keep the public widget responsive.

The live visitor and Prius counts at the bottom of this site, running as their own small AWS service. A Python Lambda and DynamoDB sit behind an API Gateway, all of it defined in Terraform and deployed by GitHub Actions with no stored keys. It's a tiny backend, but I built the full production setup around it on purpose, as my take on the Cloud Resume Challenge.
