About

Engineer first. Builder always.

Born 1991, based in Slovakia until end-2026, Thailand-bound after that. Started on the shop floor as a chassis welder at 20 and worked up through five process-engineering roles at Volkswagen and Jaguar Land Rover. Internal CATIA + 3DExperience SME, comfortable shipping production code in C# and VBA when API access is denied or there’s no off-the-shelf tool.
