Angaeli covers all things Off-Highway as a part of the marketing team at Diesel Laptops, from construction and agriculture machinery to heavy equipment diagnostics.

My role has brought me to The National Tractor Pulling Championships in Bowling Green OH, had me trekking through farms in Gilbert, SC and even sent me to a construction theme park in NJ. I spread the word about new ways that Diesel Laptops serves the Off-Highway community, and work with diesel techs to help them discover heavy equipment repair options.
