What I'm looking for

I seek hands-on HVAC roles focusing on chiller plants and BMS environments where I can lead teams, improve reliability, and deliver energy-efficient operations.

I am an HVAC specialist with over 14 years of international experience across Africa and the Middle East, focused on safe, reliable operation of large chiller plants, VRF/VRV systems, AHUs, FCUs, VFD-driven equipment, and BMS-controlled environments.

I lead and support multidisciplinary technical teams, drive commissioning, preventive maintenance and fault-finding, and use CMMS (Maximo) for work orders and asset tracking to meet SLAs and ISO procedures.

Recognized for hands-on technical depth and disciplined, results-driven leadership, I have delivered energy-efficient operations in high-standard facilities and received Foreman of the Year (2019) for performance at a major research campus.
