William Heeb
Full-Stack Software Engineer
Eight years shipping production software, from debugging Sears' internal apps to building secure,
508-compliant government systems for the Defense Health Agency. IAT Level II certified (Security+),
currently delivering the public DHA.mil platform on Sitecore and .NET. I built an AI tutor to help
myself pass Security+, then open-sourced it. I like hard problems: hardened DoD deployments, RAG
pipelines, multi-tenant SaaS architecture, and smart contracts that don't blow up.
