I began in the Aerospace industry back in 2008 and it changed my life. I was able to do international business with really great people. With intense growing passion for the industry and to deliver the best of myself to my customers, I started putting in long hours throughout the years to learn about the industry from all angles. From manufacturers, prime/subcontractors, distributors, resellers to end users. This vastly helped me understand how each business model works their everyday challenges and specific needs.

Having worked with many of the top contractors and OEM’s within the industry globally, I gained knowledge and expertise in many large programs/projects involving many unique platforms. Diversifying my knowledge on all platforms ranging from aircraft, helicopters, ground vehicles, naval vessels, sonar systems, space systems and simulators for both commercial and military sectors.
