Design Systems, Then The Last 5%

Senior frontend developer with 10+ years of shipping production apps: I ran Embroker’s UI toolkit, a library of around a hundred components powering their insurance platform, led frontend teams and tribes, and lately build multichain DeFi products.

Now back at Bloxico as an AI-Native Fullstack Engineer, building cross-chain infrastructure on Highway.

I care about design systems, testing, and the last 5% of polish.
