For a business with a problem to solve and a product to deliver. I help define what matters and take the work through implementation and release.
Discuss a product

I help businesses build useful products, improve existing systems and make clearer technical decisions. 7 years of hands-on engineering, with the right tools for the problem.

About
I’m Desmond Ngwuta, a software engineer in Nigeria. I’ve been building software for seven years, working with Java, Kotlin, Swift and Flutter across Android and iOS before moving mainly into full-stack engineering in 2024. I’ve built new products and improved existing systems, and I still write and ship code myself.
I start with the problem, choose tools that fit and aim for software people can use and teams can maintain. I use coding agents every day to trace bugs and test fixes, and I review what goes out.
