Agunechemba Ekene
Web Innovator & Trainer
I design and build web experiences that help businesses show up with style. I’m driven by the thrill of turning ideas into digital spaces that feel modern, responsive, and just a little bit ahead of the curve.
As the founder of Pepe Programmers Hub and the mind behind Firstac Academy, I’ve taken my love for innovation far beyond the glow of the monitor. Each year, I run two free international bootcamps that bring together curious minds from around the world. Hundreds of teens have passed through these sessions.
My training journey spans Nigeria, the UK, and the US, shaping learners through practical challenges, fun exercises, and projects that make them ask, “Wait… did I really build that?”
