Presentation

I am a Mobile App & Frontend Engineer with over 4 years of experience building high-performance, scalable web and cross-platform mobile applications for healthtech, logistics, and consumer platforms.

What I Offer:
- Cross-platform mobile apps using Ionic Framework (with Capacitor/Cordova) — deploy once to iOS and Android with native-like performance.
- Modern frontend development with Angular, React, Next.js, and TypeScript.
- Reusable component systems and design systems using Storybook.
- Performance optimization — refactoring legacy code, implementing lazy loading, caching, and build optimizations.
- Testing & code quality — unit & end-to-end testing with Jasmine/Karma, Cypress, and enforcing TypeScript strict mode.
- Light backend integration with NestJS and REST APIs when needed for full-featured solutions.

Key Achievements & Approach:
- Led the complete Ionic rewrite of a fleet management app (Instanta Fleet v2.0), significantly improving stability and user experience.
- Refactored Angular modules in a healthtech platform (SmartClinic), boosting performance through lazy loading and caching.
- Introduced Storybook for standardized UI components and improved design-engineering collaboration.
- Recognized as Engineer of the Quarter for technical leadership and ownership of core frontend initiatives.
- Strong experience in remote, cross-functional teams — collaborating with designers, backend engineers, and QA to deliver production-ready features.

I specialize in turning complex ideas into clean, maintainable, and delightful user experiences that feel native on mobile while keeping development efficient and scalable.

Whether you need a new mobile/web app built from scratch, legacy codebase modernization, performance improvements, or ongoing frontend maintenance — I deliver reliable, high-quality results.

Open to:
- Full project development (MVP or complete apps)
- Refactoring & optimization gigs
- Component libraries / design systems
- Hourly or fixed-price contracts

Let's discuss your project! I'm based in Nigeria (GMT+1) and available for remote collaboration worldwide.

Feel free to message me with your requirements — happy to provide a detailed proposal and timeline.
