Also known as Chama

I'm a solo developer who designs, engineers, and ships mobile and desktop applications independently, from the first line of code to live in the App Store.

What I do

  • Solo development. I own every layer of a product: design, code, CI, release, and support.

  • Ship to production. Every app is live in the App Store or Google Play, used by real people.

  • Privacy by default. I build tools that process data locally. No cloud by default, no telemetry unless it serves the user.

  • Performance-conscious. Native implementations where it matters: real iperf3 binary, real on-device ML inference.

My approach

  • Product + engineering. I think about what the product needs before writing the code. Features earn their place.

  • UI/UX + implementation. The interface is part of the product. I design and implement it, using platform idioms where they work.

  • Own the full release cycle. App Store review, compliance, localization, crash monitoring. I handle all of it.

  • Keep it maintained. Apps I ship get real updates. I respond to reviews and support emails personally.
