Meet the founders
Durin is built by two founders with complementary skills and a shared belief: that technology should reduce friction, increase trust, and open doors for the people who need it most.
Caleb Ogundiya
Co-founder & CEO
Caleb Ogundiya
Co-founder & CEO
Caleb is an innovative and solutions-driven full-stack software engineer with over a decade of experience delivering high-performance, scalable systems across public and private sectors. He currently also contributes to the UK's Department for Work and Pensions as a Software Engineer on the Payments Team — architecting and deploying microservices for government-scale financial platforms.
His expertise spans backend development in Node.js, Python, and TypeScript; frontend in React and Next.js; cloud and DevOps on AWS and GCP; and blockchain engineering. He holds a BSc in Systems Engineering from the University of Lagos, a Certified Ethereum Developer credential from ConsenSys Academy, and has built everything from fintech microservices to humanitarian fund disbursement systems. At Durin, Caleb leads product and engineering — and is the driving force behind Seli, the verified immigration marketplace he built to remove the fraud and friction millions of Nigerians face every year.
