About Me
I’m Tolu Okunjoyo, a Frontend Engineer building scalable, high-performance web applications with React, Next.js, and TypeScript.
I specialize in dashboards, data-heavy interfaces, and complex UI systems. I’ve shipped production features across fintech dashboards, e-commerce apps, AI-powered tools, real-time messaging, and video conferencing platforms, including complex SDK integrations.
My focus is on delivering maintainable, production-ready applications that solve real user problems. I’m now expanding into React Native to bring my web experience to mobile platforms.
