Professional Summary

I am a senior full-stack engineer with more than 12 years shipping production software, including a no-code platform for building AI agents at Zaia and an AI-native delivery loop at Coinbase. I use Claude, Cursor, and Codex from the first conversation through spec, implementation, review, and release.

I am not looking to demo prompts. I want to help AI product and platform teams ship agents, tools, and interfaces that hold up in production: typed contracts, tests, and human-in-the-loop surfaces.

Most recent role: Senior Software Engineer at Coinbase. I am targeting AI product, agent, and platform teams.
