Backend Developer (Node.js/NestJS) | Computer Science Graduate | AltSchool Africa Alumnus
I build backend systems — APIs, databases, and the invisible infrastructure that keeps applications reliable and secure.
I hold a Computer Science degree and recently completed a year-long diploma in Backend Engineering at 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 background 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.
CribDirect — A real estate and property management platform connecting landlords, landowners, and tenants.
- Stack: NestJS, TypeScript, PostgreSQL, Redis (planned), Docker (planned)
- Focus: Role-based access control, lease management, payment tracking, and production-ready architecture
- Status: In active development. Learning and building in public.
I'm documenting the journey — schema decisions, authentication flows, caching strategies, and the bugs that taught me the most.
- RESTful APIs with Node.js, Express, and NestJS
- Authentication systems with JWT, refresh tokens, and role-based access control
- Database schemas with PostgreSQL, MySQL, and MongoDB
- Real-time features using WebSockets (Socket.io)
- Secure applications with input validation, rate limiting, and security best practices
- Tested code following Test-Driven Development
Languages & Runtime Node.js • TypeScript • JavaScript • SQL
Frameworks & Libraries NestJS • Express • Socket.io • Joi • JWT • Jest
Databases PostgreSQL • MySQL • MongoDB
Currently Deepening Docker • Redis • BullMQ • System Design • CI/CD
I build in the open and document what I learn — bugs, breakthroughs, and architectural decisions. My repos show the full picture: finished projects, works-in-progress, and a learning journal where I track gaps I'm filling.
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.
