Implemented a wallet system with WebSockets for real-time balance updates. Created Redux slices to manage authentication, savings, and payments.

Developed and maintained high-performance, cross-platform React Native applications for Android and iOS, ensuring seamless user experiences.

• Leveraged memoization (React.memo) and callback optimization (useCallback) to reduce component re-renders by 30%, improving app performance.
• Implemented lazy loading and code-splitting strategies, decreasing app load time by 25% and boosting user retention by 10%.
• Optimized animations and transitions using libraries like Reanimated 2, resulting in a 15% increase in app store ratings.
• Collaborated with UI/UX designers to implement responsive and intuitive designs, contributing to a 20% increase in user engagement.
• Designed and integrated a wallet system and integrated WebSockets to enable real-time balance updates and transaction notifications for users.
• Implemented account funding from bank to the wallet system to enable users carry out their daily transactions on the platform such as: Buy airtime,purchase data, pay for cable etc.
• Reduced balance update latency from 5 seconds to under 500ms, improving user trust and engagement.
• Implemented event-driven architecture to handle high-frequency transactions, ensuring system reliability during peak loads of 1,000+ updates per second.
• Enhanced user experience by providing instant feedback on transactions, leading to a 20% increase in user retention.
• Collaborated with back-end and QA teams to ensure seamless integration and rigorous testing, achieving 99.9% system uptime.
• Designed and implemented Redux slices to centralize state management for authentication, savings, and payment modules, improving code maintainability and reducing state-related bugs by 30%.
• Utilized Redux Toolkit to streamline state logic, reducing boilerplate code by 40% and accelerating development timelines.
• Enhanced application performance by optimizing state updates and minimizing unnecessary re-renders, leading to a 15% improvement in app responsiveness.
• Integrated async thunks to handle API calls for user authentication and payment processing, ensuring seamless data synchronization and error handling.
• Collaborated with back-end teams to ensure consistent state management across the application, contributing to a 20% reduction in integration issues.

• Enhanced application performance by optimizing state updates and minimizing unnecessary re-renders, leading to a 15% improvement in app responsiveness.
• Integrated async thunks to handle API calls for user authentication and payment processing, ensuring seamless data synchronization and error handling.
• Configured and deployed app to production from xcode to apple store through idmsa.
• Configured and deployed app to Google play store using expo build while ensuring some configurations are done on android studio.
• Lead junior developers and team mates to design highly responsive and optimized screens.
• Designed the mobile architecture for the team to follow, thereby ensuring complaince to development standards.
