About

A mobile engineer who owns the full release path.

I’m Tejiri, a React Native developer focused on shipping real products — not demos. From recipe discovery and entertainment to social, commerce, and cooperative finance, I take apps from architecture through UI, integrations, and store launch.

I care about motion that feels native, state that stays predictable, and security that holds up when money and identity are on the line.

  • Cross-platform, native feel

    One React Native codebase, polished iOS and Android releases.

  • Architecture that scales

    Typed screens, query caches, and stores that stay maintainable.

  • Live on both stores

    Apps published on the App Store and Google Play, ready for users.
