Not a straight line.
I started in Economics. Geopolitics. Finance. I thought that was the path — understanding how the world moves money and power. Then I realized the real leverage was in the systems underneath all of it.
Now I'm at African Leadership University in Kigali, studying Software Engineering. Building at the intersection of security, AI, and African digital infrastructure. Documenting the process along the way.
I'm Cameroonian. I operate under @builtbykoffi — a dark, minimal brand built around tech, media, and what it means to build seriously from Africa.
