I lead Start Designs, a 50+ person studio — so you can hire me as a senior individual contributor, or scale up to a full design + frontend + backend + mobile team on the same contract. No handoffs to strangers, no outsourcing. WHAT I BUILD - UI/UX & product design — Figma, design systems, wireframes to production-ready interfaces, landing pages, mobile-first responsive design. - Mobile apps — React Native and Expo for iOS and Android from a single codebase. Currently shipping a production Expo app to both the App Store and Google Play.

HOW I WORK Most projects fail in the scoping, not the coding. Before I write anything, I map your requirements into a clear technical plan — scope, architecture, milestones — so you know exactly what you're getting and when. You get one accountable point of contact, daily communication, and clean, documented, maintainable code.
