// ABOUT

Who's behind
Tech Gravity

I'm Minghao Ni, a solo iOS developer with a passion for building apps that feel great to use. I work across the full stack of iOS development — from SwiftUI interfaces to Game Center integration and App Store publishing.

My work lives at the crossroads of utility and craft. I care deeply about performance, accessibility, and pixel-level detail. Every app I ship under Tech Gravity is something I'd want to use myself.

When I'm not coding, I'm usually sketching pixel art or playing the puzzle games that inspired PixelSudoku.
