About Me

I'm a Software Engineer with over 4 years of experience designing and building full-stack web applications, internal tools, and system integrations. I bring a strong mathematical foundation and a product-oriented mindset to everything I build.
I hold a B.Sc. in Mathematics from the University of Abuja, which gives me a unique analytical edge when approaching complex engineering problems. I enjoy working across the entire stack — from crafting pixel-perfect frontends to architecting robust backend systems.
