Product-minded software developer

I build software
people want to
keep open.

Hey, I'm Navid. I build fluid cross-platform products with Flutter, Swift, Python, and the web. I care about sharp interfaces, thoughtful architecture, and software that earns its place on your screen.

02 / BEHIND THE BUILD

Doing it for the
love of the game.

I build because I enjoy the whole process: chasing an idea, figuring out the tricky parts, and getting the small details right. There is always something new to learn and something worth making better. That is what keeps me coming back.
