A civil engineer by training, Keba Bachir Mbaye began his career with SICRA, a subsidiary of the Vinci Construction group, before moving to Senegal to join the Consortium d'Entreprise (CDE), a national leader in the construction sector.

In 2018, driven by a desire to play an active part in transforming the built environment in West Africa, he co-founded Atelier KALM, where he acts as project economist and consultant-developer. He also founded KOS, his own general construction company, in order to fully control the execution of the projects he develops.

Sensitive to environmental issues, it works to integrate innovative and responsible construction solutions, favoring materials and techniques that significantly reduce the energy footprint of buildings.

As a developer, we support project owners from the earliest stages of the project, creating coherent, sustainable and cost-effective programs - with constant attention to budgets, deadlines and quality of execution.
