About
Building with purpose.
I'm Delight Sheriff — a software engineer who builds products people actually want to use.
My foundation is full-stack: React, Next.js, Node.js, TypeScript, and MongoDB. I have been expanding into cross-platform mobile with React Native and Expo — applying the same product thinking that shaped my web work to mobile-first experiences.
I care about the details users feel but rarely name: fast load times, intuitive flows, interfaces that do not fight back. Good software is invisible in the best way.
I work well in collaborative environments and move quickly without sacrificing quality. Whether it is a client MVP or a long-term team build, I ship things that last.
Building something ambitious? Let's talk.
