Astrit Bislimi

I'm primarily a frontend engineer, and I understand the backend deeply enough to own features across the client/server boundary.

I'm a Senior Front-End Developer with 5+ years of professional experience building production web and mobile applications in React.js, Next.js, and React Native.
