Building things
that actually work.

I'm a full stack developer and R&D manager with a passion for building robust, scalable software that solves real problems. I bridge the gap between technical depth and product thinking — from database design to pixel-perfect UIs.

I love working at the intersection of product and engineering, leading teams, defining architecture, and still shipping code that matters.
