Senior Software Engineer: AI Developer Tools, Agent Workflows, Product Platforms

Senior software engineer with 10+ years across platform, frontend, backend, and developer workflows. I build agent tooling with a bias toward the parts that make it useful in real work: intuitive developer surfaces, clear boundaries, reliable verification, human review, and systems that are understandable when something goes wrong.
