01 — About

Building intelligent solutions for Africa and beyond.

I'm Lokossou Dossou Kajarnak, a student and AI Builder from Benin, passionate about artificial intelligence, machine learning, data and software development. I build my skills primarily through self-directed learning and shipping concrete projects.

My goal is to turn real-world problems into accessible technological solutions, particularly in the African context. I'm not aiming to look like a senior engineer — I'm a curious builder in progress, and that's my advantage.
