Professional overview
Where aerospace engineering, intelligent systems and digital technology converge
Work across four connected disciplines: aeronautical engineering and simulation, unmanned aerial systems, applied artificial intelligence, and full-stack software. Each area below links to the projects, research and credentials behind it — expertise demonstrated through work, not asserted through adjectives.
