What I'm looking for

I’m looking for engineering work on complex, high-impact products where I can raise quality, ship fast without cutting corners, and use AI to multiply outcomes. I value growth, pragmatism, strong devops, and a culture that mentors and shares.

I’m an Associate Principal engineer with 13+ years in the game, driven by a lifelong passion for automation. I thrive on complex problems, ship at the highest standard, and build for growth—using AI as a multiplier, not a crutch.

I’ve led teams across every size, starting with a remote startup founder journey and moving through high-leverage engineering environments. I’ve architected and shipped major client systems, including a composable rich text editor and an end-to-end video feature delivered in two weeks, plus mobile CI/CD pipelines that helped me ship polished experiences faster.

I care deeply about quality and momentum: I led a quality overhaul of an iOS app to reach a showcase spot at WWDC, and I implemented devops systems that accelerated cycles by 400%. I also give back through open source, conferences, and mentoring, because I believe great software lives at the intersection of ambition and pragmatism.
