What I'm looking for

I’m looking to build high-performance, secure cross-platform wallet/fintech mobile apps—shipping real-time features, authentication flows, and lightweight responsive UI while collaborating closely with product, UI/UX, and backend teams.

I’m a Senior React Native Developer with 7+ years of experience designing, developing, and maintaining cross-platform mobile applications for iOS and Android. I bring a strong background in React Native, React.js, Redux, TypeScript, and JavaScript ES6+, with hands-on REST API integration, Socket.io/WebSockets, Firebase, and third-party SDK integrations.

In my current role as a Senior React Native Consultant / Senior Mendix Developer at Inova8, I develop and maintain mobile and web applications, build reusable UI/UX-aligned interfaces, integrate APIs and SDKs, and support scalable architecture, troubleshooting, and performance improvements. Previously, I delivered production React Native apps at Scorpbit Technologies, and also built mobile application features at The Digit-Tech and TechMelo—always collaborating closely with product, UI/UX, and backend teams to ship intuitive, lightweight, secure experiences for demanding fintech and wallet environments.
