01About

Curiosity led me across the whole product.

I’m Charlot Joël DEDJINOU, a software engineer based in Benin. I started with web development, then followed the needs of the products I was building into mobile, cloud infrastructure, identity, computer vision and connected systems.

This breadth is not a collection of tools. It helps me understand a system as a whole, make sound technical choices and carry an idea through to a working product.

02Career

Responsibility grew with the systems I built.

My path has expanded through products with increasingly broad technical and operational needs. Each role added a new layer: interface quality, mobile delivery, backend architecture, connected systems, infrastructure, identity and security.
