About
CS graduate from San Diego State University with hands-on experience shipping iOS apps to the App Store. I built Keyoku — a flashcard app powered by Apple's on-device AI — from idea to launch. I'm currently expanding into web development and looking for iOS or full-stack roles where I can keep building products people use.
