Jamie Claudeo Jr. started turning wrenches under his fathers watchful eye when he was just 10 years old climbing in and out of large commercial boilers.  By end of high school he was attending vocational school for electrical trades and before graduating succeeded in taking first place at the state level SkillsUSA competition.  Having a love for engines and machinery, he eventually moved into working on large trucks for Peterbilt after attending Universal Technical Institute in Pennsylvania and Arizona.  After Hurricane Sandy decimated the northeast in 2012 he eventually made his way into Power generation, working for a small company out of NJ.  His strong understanding of both electrical and engines allowed him to move up quickly – taking on large projects, and hard to troubleshoot problems across several states until eventually choosing to start his own business in 2022.

During his free time, Jamie enjoys traveling the world, dark beer, hiking, rock climbing, running and tinkering with old machinery.  On more quiet relaxed evenings you can find him curled up on a giant bean bag chair enjoying a good video game.
