About

Engineer building reliable systems, intelligent products, and open financial infrastructure.

I’m Sunday Ibrahim Ijai—also known as Ibrahim Sunday and Ibrahim Ijai—a self-taught software engineer with over five years of experience building web and mobile products, AI-powered tools, smart contracts, and reliable backend systems.

My background in mechanical engineering shaped how I approach software: understand the system, reduce unnecessary complexity, and make every component earn its place. Today, I apply that thinking to fintech, blockchain protocols, AI, and developer infrastructure.
