Here’s a polished and professional version of your CV summary:
I am currently employed at L&L Consulting Services as an on-site Auto Electrician, where I am responsible for the maintenance and servicing of all TMMs (Trackless Mobile Machinery) and LDVs (Light Delivery Vehicles). I provide 24/7 breakdown assistance to ensure minimal operational downtime. As the sole technician on site, I manage parts procurement, handle client queries, and oversee the overall management and performance of TMMs.
If you want, I can also make it shorter, more technical, or tailored to a specific job you’re applying for.
