A mobile developer building toward Application Security.

I am Oshiokhua Rhema, a cross-platform mobile developer from Delta State, Nigeria, building React Native and TypeScript apps for clients and teams around the world. I own features end to end, from interface and state to REST APIs, push notifications, and offline support, and I'm currently studying toward Application Security through OWASP and secure coding practices.
