About Me

Backend Developer Computer Science AltSchool Africa Location

I build backend systems — APIs, databases, and the invisible infrastructure that keeps applications reliable, secure, and fast.

I hold a Computer Science degree and a diploma in Backend Engineering from AltSchool Africa, where I specialized in Node.js. Before software, I spent years in Nigeria's local tech ecosystem — repairing computers, teaching at a training school, and building websites for small businesses. That experience taught me how to debug systematically, communicate with non-technical clients, and stay calm when systems fail.

Now I bring those instincts to backend engineering.


🚧 Currently Building

CribDirect — Real Estate & Property Management Platform

A platform connecting landlords, landowners, and tenants — handling property listings, lease management, payment tracking, and maintenance requests.

NestJS TypeScript PostgreSQL Redis Docker BullMQ

  • Focus: Role-based access control, lease lifecycle, payment tracking, and production-ready architecture
  • Status: In active development. Building and learning in public.

I'm documenting the full journey — schema decisions, authentication flows, caching strategies, and the bugs that taught me the most.

📚 Learning in Public

I build in the open and document what I learn. My repos show the full picture:

  • CribDirect — My flagship project, a real estate platform built with NestJS and PostgreSQL
  • Learning Journal — Notes on PostgreSQL, Docker, system design, and debugging stories
  • AltSchool Projects — APIs, authentication systems, and real-time features built during my diploma

If you're a backend engineer who remembers what it felt like to build something real for the first time, I'd love to connect — especially if you have feedback on CribDirect.
