## About

```text
At WannaPlay, I develop and maintain three iOS and Android applications with React Native. I implemented subscription and in-app purchase flows, integrated Unity for game launches and data exchange, and migrated React Navigation from v3 to v7.

I also developed and maintained two web products, one of which grew to 2–3K new users per day. I owned client-side web payment integrations with Stripe, Recurly, Solidgate, and TrueGate, and worked on onboarding flows, web push notifications, and real-time AI chat over WebSocket.

For the last six months at WannaPlay, I served as Lead Frontend, coordinating two developers, planning tasks and releases, and conducting 1:1s and performance reviews. I also reviewed code for a frontend team of 4–5 developers and participated in technical decisions.

Previously, at Tactil LLC, I was the primary React Native developer for four multilingual iOS and Android applications. I implemented subscriptions, integrated the GPT API for educational content, and developed a native iOS widget in Swift. At NostrCorp, Inc., I built a React application for real-time data monitoring and ported a web application to Android using Cordova.
