<fullstack/>

Hey! I'm Jaymar Raquepo — designer and programmer rolled into one, with 19 years of experience shipping web, mobile, backend and embedded applications.

I take products from interface design through REST APIs, databases, deployment and app-store release.

Recent work spans a multi-tenant public Wi-Fi platform, an AI-powered market research platform, logistics tracking and telehealth. Earlier work includes e-wallets, bills-payment and remittance apps for OFWs, and San Miguel brand websites. Comfortable working directly with clients, UX and product teams.

Want to see some of my latest work? Head over to my Quick Portfolio to check it out. I'm always excited to collaborate on new projects—let's make something awesome together!
