What I'm looking for

I'm seeking a Backend Engineer or AI Trainer contract role where I can apply my backend experience to feature implementation and resolving system bottlenecks.

At Codey Craft Africa, I delivered 20+ production web applications and built backend services, database designs, and deployments. I implemented JWT authentication with role-based access and integrated Jenga STK Push and M-Pesa Daraja into payment and payroll workflows.

As a freelance web developer, I delivered 40+ websites for small businesses and individual clients, from planning and development through testing, deployment, and maintenance. I also developed a donation portal and digital intake forms for Leave No Veteran Behind.
