What I'm looking for

I'm looking to own end-to-end engineering problems, build scalable cloud-native systems, and use applied AI workflows to improve delivery speed and code quality.

At Pixida (MAN), I build C#, .NET, AWS Lambda, and DynamoDB services for vehicle diagnostic and ECU management systems, alongside React/TypeScript interfaces that help engineers track configuration changes. I also use AI-assisted and multi-agent development workflows to speed feature delivery and reduce code review cycles.

Previously, I built secure payment gateway and terminal-management microservices at Emerging Africa Group (Fundall), logistics applications at GIGL, and helped transition Parkway's core application from Java to .NET. I enjoy owning problems end to end, from requirements and architecture through deployment, reliability, and team support.
