Practical, focused on results, careful with the small stuff.
I'm Oladele Ibraheem — Lagos-based, better known online as Big Brain. I help founders and teams turn rough ideas into real products people can actually use. The part I love most is the messy beginning: when the idea is still a half-sentence, the deadline is already real, and someone has to figure out how the whole thing should look, feel, and work.
Across three years I've shipped across brand, fintech, gaming, retail, and AI tools — building everything from full-stack web apps to brand systems for businesses that want to look like what they charge for.
I design with the happy path, every unhappy edge case, and the instrumentation to tell them apart.
The work I'm proudest of is the work where the user never noticed how much thought went into it. Quiet design. Honest products. Brands that earn the room they take up.
When I'm not building, I'm writing about it on Substack and Medium, running the @xbigbrainnx personal brand, and slowly shaping Wintech Studio into the kind of agency Lagos deserves.
