Full-Stack Engineer — Backend · AI Agents · Security
Self-taught since 2020. Shipping to production since 2024. I build the systems that run underneath things — and the AI agents that keep working after everyone else has logged off.
Got into coding in 2020, during COVID, after watching dev bash build genuinely cool stuff — haven't stopped since. Years of building without real users on the line, then in 2024 I started pushing things to production — real users, real traffic, real consequences. That's the part that actually teaches you anything.
Today the work spans the full stack: React and React Native on the front end, Node and Express underneath, RabbitMQ and Redis holding the busy parts together, and a growing practice building AI agents — systems that don't just answer questions but go do things. I also spend time on the other side of the fence, penetration testing and vulnerability auditing, because you write more careful code once you've broken a few systems yourself.
An e-commerce and sales-management platform for African small businesses — spin up a store, manage inventory and orders, take card and bank-transfer payments, and sell straight through WhatsApp, with Ola (its AI) handling product questions and customer replies. I handle the backend: API design, data layer, and the infrastructure that keeps it running in production.
Deliver anything across your city in minutes: Patchride instantly connects you with trusted logistics providers nearby to get a package, document, or product picked up and delivered. Same story: backend engineering end to end, built to stay up under real traffic.
An AI agent that does the least pleasant part of running a small business for you: chasing down unpaid invoices. It watches what's overdue and follows up automatically — polite, persistent, and awake at hours you're not.
Open to conversations about backend work, AI agents, or a security review of something you'd rather I found the hole in before someone else does.
