I designed, built, and shipped Lavia, my AI wellness app on Google Play, and brought in real testers and paying subscribers. I developed its React Native app and Firebase/Node.js backend, with AI chat, Google Play subscription verification, and support for 38 languages.

At ThreeSteps, I built the front end of a dental clinic web application from Figma designs, including its dashboard, home page, navigation, and responsive layouts. At Digital Silk Road, I built a Node.js crypto-trading automation service and an API proxy to keep the service stable.
