Senior Frontend Engineer focused on building scalable, high-performance web and mobile applications.
I specialize in frontend architecture, system design, and performance optimization using React, Next.js, and React Native.
I build production-ready systems that go beyond UI—focusing on scalability, maintainability, and real business impact.
One of my key projects includes designing and building an internal inventory and CRM system that reduced material loss and saved over ₦20M within 4 months.
