## About

```text
At Open Wallet, I was the sole iOS developer on a self-custodial crypto wallet combining MPC-based key management and fiat banking. I worked on its modular iOS 17+ codebase.

Before that, I built the in-store shopping experience for Maxima and location-based games for Loquiz. Earlier, I developed iOS apps for Bolt's rider app and Wise before both brought development in-house.

At Coodly LLC, I shipped my own apps, including Showdown, a poker hand tracker with CloudKit-based hands backup. My releases have spanned games, health tracking, and productivity tools across iPhone, iPad, Mac, and Apple TV.
