At HelpMe-AI, I built and maintained a cross-platform React Native and Expo application covering authentication, chat, wallet, services, payments, and AI-powered workflows.

I implemented secure onboarding and session handling with token refresh, and added location-aware features using Expo Location and React Native Maps. I also integrated Paystack and Flutterwave payments, including verification.

At JJTech Booking — Multi-Transport Platform, I built React Native and Expo booking experiences for flights, cars, and boats under a technical spec. I integrated REST APIs and Paystack payment flows and debugged mobile issues ahead of release.

My other work includes maintaining the existing React Native/Expo codebase at TradeFaire Marketplace Application, building real-time marketplace interfaces at ServiceHub, and contributing to payment and delivery logic at Vaultr. I work primarily with TypeScript and am familiar with backend API work in Node.js and Express.js.
