Building digital productsthat people actuallylove to use.
I'm a Full Stack Developer with over two years of experience crafting scalable web and mobile applications. My focus is on React, Next.js, and Node.js — but I care most about the end-to-end experience: from the first line of code to a smooth App Store release.
