Working on agentic systems & orchestration at a stealth AI wellness startup.

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.
