Open portfolio SupportingDevOps & Cloud Engineer

Open portfolio High-valueBlockchain & Web3 Developer

Open portfolio Niche magnetFlight Simulation Engineer
6-DOF sim / C++ / XR engineerA remote-available engineer who has actually shipped full-motion 6-DOF FTD integration — SimConnect/Prepar3D, Brunner control loading, motion platforms, glass-cockpit EFIS and Varjo XR — a skill set almost nobody in the remote contractor pool can honestly claim.
