Automation Team Lead Engineer

Building automation and QA strategy across Web3 products (on-chain and off-chain), with a strong focus on reliability, debuggability, and fast feedback in CI. Lately, I’ve been experimenting with AI tools and workflows, and I write about those experiments and lessons learned here on this GitHub Pages blog.
