What I'm looking for

I’m looking to grow in mechanical maintenance and alternative-fuel conversion work—delivering reliable equipment performance, reducing downtime and fuel consumption, and operating with strict HSE compliance in hands-on, engineering-driven environments.

I’m a Mechanical Engineering Technician/Mechanical Engineer with hands-on experience in oil & gas facilities, heavy equipment maintenance, and alternative fuel system conversion. I’ve worked on LNG/CNG engine conversion, diesel engine diagnostics & overhaul, and preventive maintenance strategy implementation to improve equipment reliability.

In my current role at De-Sadel Consortium, I contributed to conversions from gasoline/diesel to LNG and CNG systems and Nigeria’s first LNG-diesel dual fuel locomotive conversion project. I diagnose fuel delivery and pressure/ignition issues, create technical documentation and safety guidelines, and ensure strict HSE compliance during installation and testing.
