Software engineer. End to end.

I'm Oluwaseun David Ajiboye, a software engineer in Ibadan, Nigeria. I build complete products, from the screen people tap to the server it runs on, and I care about every layer in between.

That range is the point. I can sit with a founder to shape a first release, design the interface, model the data, write the API, wire up payments, and put it live, without the slow handoffs that usually sit between those steps. Whether it's a multi-tenant platform or a website that simply has to look and feel right, I start the same way: understand what's needed, then build the simplest thing that solves it well.

I've shipped workforce and payroll software, booking and commerce products used by real customers, content platforms clients run day to day, an AI-assisted WhatsApp sales tool, and a cryptographically signed credential system. On the surface I sweat the details people feel: speed, clarity, motion. Underneath, I make sure the important rules hold, from payments verified on the server to changes that get reviewed and failures that recover.
