Engineering solutions that bridge disciplines

Engineering Excellence

With 15+ years of hands-on engineering experience, I specialize in creating practical solutions that span from embedded automation to 3D graphics and native applications.

My toolkit includes Siemens NX, SwiftUI, C++, Delphi, Arduino, and Unityβ€”allowing me to own every layer of a project from concept to delivery.
