Über mich

Web and Mobile App Frontend Developer (Self-taught!). I specialize in React Native, Expo, Tamagui, and Next.js (TypeScript). My developer journey for client projects began in 2004 with HTML, CSS, and JavaScript, followed by over a decade of WordPress development. I have experience developing web projects from the sketch with React.js, React Native for Web, Gatsby, Wix, and Shopify. In addition to my core React expertise, I have experience building and delivering hybrid apps to app stores using Cordova, Ionic with Capacitor (Angular), and Flutter (Dart). Before that, I worked in financial and startup consulting, and in the marketing industry.
