<p>I'm a <strong>Software Engineer III at ASML</strong> in Wilton, CT, where I work on the platform that 1,000+ engineers build on: Bazel build infrastructure, CI/CD with artifact provenance, and an internal agent platform of 15 MCP servers that I prototyped independently and the org adopted.</p>
<p>I studied computer science at the <strong>University of Michigan</strong>. Outside work I build local-first tools — software that runs on your machine, answers to you, and keeps your data yours.</p>
