Hi! I’m Daniel,
full-stack builder
I turn ambitious ideas into AI-powered SaaS, web apps, and growth systems — with the product thinking to make them useful and the engineering to make them real.

About me

A pragmatic partner

I’m Oyinloluwa Daniel, founder of Cipher Development. I work with solo founders, agencies, and growing teams to translate unclear product ideas into focused, production-ready software.
That can mean shaping the scope, designing the flow, shipping the full-stack application, or making a half-built product stable enough to grow. I care about fast movement, clear communication, and work that holds up after launch.

He has taken my application from a little idea to a fully functional program in the short time we have worked together. He works SO hard and is so respectful. I highly recommend working with him!”

No drama.
