At Yellot, I define frontend architecture and technical standards for YellotMob while staying hands-on with development and releases. I partner with product, design and backend to turn requirements into technical plans.

Since joining Yellot in 2023, I’ve driven the frontend side of YellotMob’s rating increase from 3.4 to 4.9 stars on the App Store and Google Play, alongside growth to nearly 3,000 reviews. I also helped scale monthly revenue nearly 100x.

As Senior Frontend Developer, I led YellotMob’s development with React Native, Expo and TypeScript. I restructured the codebase into a feature-based architecture, built reusable components and improved performance with code splitting and lazy loading.

Earlier, I built web and mobile products at CreativeCode, migrated legacy applications from jQuery to React at GreenLab Food, and developed business web applications with Node.js, Express and MySQL at Evergreen Vidros.
