a bit about me
I鈥檓 Sunday Ibrahim Ijai, also known as Ibrahim Sunday and Ibrahim Ijai. I鈥檓 a self-taught software engineer with 4+ 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, ZK, AI, and developer infrastructure.
