Rhema Emmanuel-Great Oshiokhua

Mobile Developer

Global

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.

A BSc in Software Engineering at Babcock University ran alongside years of freelance video editing and graphic design, plus a networking internship at NNPC, Warri, hands-on with LAN/WAN and VPN infrastructure. React Native became the focus once mobile development turned from a side interest into paid work: shipping Maxi Healthcare for a US home care provider, volunteering on Medscan with Trakiva, and taking on independent clients. That work now runs through KDV Studios (Khua daVinci Studios), alongside ongoing study toward Application Security through OWASP and secure coding practices.
