Currently working at Vital Beats and Building experiments in my spare time.

I'm a software engineer with a passion for mobile app development. I've been using React Native for the past 8 years and along the way, I've had the pleasure of working with some amazing companies and teams.

I've shipped React Native apps that have served 2M users at  Solid Starts , contributed to one of the  most popular React Native boilerplates  at Infinite Red  and I continue to deliver high-quality mobile apps for clients in fintech, healthcare, and other industries.

When I'm not writing code, I enjoy traveling, walking my dog Nata and photography.

    React Native Engineer ·  Honeycomb Labs

    With my proficiency in React Native, I've greatly enhanced Honeycomb Labs' app navigation performance, delivering a lag-free experience. Integral to this role was moving several animations to reanimated while leveraging worklets to not block the UI thread. I've also optimized a lot of React components that were re-rendering unnecessarily causing a drastic drop in FPS.

    Solid Starts is a mobile app that provides parents with evidence-based information on introducing solid foods to their babies. The app is built with React Native and uses AWS services for data storage and authentication. I was responsible for the development of the app and the backend services.

  2. Ignite Bowser

    Ignite Bowser is one of the most popular React Native boilerplates out there. I have maintained this project along with other core members of Infinite Red. Notably, I upgraded the navigation library for React Navigation V4 to V6 which involved a complete re-write of the navigation structure due to breaking API changes.
