About

I’m a Senior Product Engineer/Design Enginer/UX Engineer with over eighteen years of experience building digital products at the intersection of design and engineering. I care deeply about crafting interfaces that are both beautiful and accessible — systems that feel effortless to use and are a pleasure to maintain.

My background spans frontend architecture, User-centered design and full-stack product development. I’ve worked with early-stage startups and scaled teams at big corps, always with the same focus: understanding the problem before writing a line of code. I believe the best software is built when product teams, engineers and designers think together from day one.
