Senior Full Stack Engineer
From early-stage startups to Fortune 10 enterprises — building systems at every scale for nearly two decades.

Senior Full Stack Software Engineer with deep experience across the full stack — from crafting intuitive front-ends to architecting large-scale backend systems. I work well independently, thrive in ambiguity, ship quickly without breaking things, and regularly use AI as a collaborative tool in my workflow.

From early-stage startups of under 10 people to Fortune 10 enterprises, building systems at every scale. Greenfield products, high-availability distributed backends, and everything in between — for nearly two decades.
