Leadership · OHM WORKS

The drone engineering studio I wished existed.

I founded OHM WORKS to address a simple frustration: in West Africa, there was no drone engineering studio combining European technical rigor with a deep understanding of the Beninese context and the sub-region.

OHM WORKS operates from Cotonou with a team of photogrammetry and GIS engineers, ANAC-certified pilots, expert surveyors and LiDAR specialists. We work indifferently for heritage institutions, integrated agribusiness operators, public clients, construction design offices, mining operators, telecom carriers and forestry managers — each time with the same rigorous protocol and the same accuracy standards.

We don't deliver drone photos. We deliver the data our clients need to decide — fast, accurately, with full traceability.
