Mechanical Engineer focused on reliable rotating equipment maintenance and industrial troubleshooting.
NigeriaWhat I'm looking for
I’m a resourceful and adaptable Mechanical Engineer with proven experience in mechanical systems maintenance, rigging operations, and industrial troubleshooting. I bring strong knowledge of rotating equipment, HVAC systems, and project coordination, with a proactive attitude toward delivering high‑quality technical work.
In my recent roles as a Mechanical Technician, I’ve handled installation, alignment, and routine maintenance for mineral‑processing equipment including pumps, motors, conveyors, ball‑mills, cyclones, magnet separators, valves, thickeners, and agitators. I diagnose mechanical faults, execute corrective actions to minimize downtime, and monitor vibration levels, lubrication systems, and wear patterns to improve reliability and operational efficiency.
I also strengthen safety and documentation: I collaborate with process engineers and safety teams to maintain compliance, and I document maintenance activities and prepare daily reports. Whether it’s rigging and lifting, mechanical troubleshooting & root cause analysis, or HVAC servicing (refrigeration and air conditioning), I’m known for attention to detail, safety compliance & hazard analysis, and clear communication.
