About
The person and principles behind Pius Technologies
Fabio Marques
CTO · Full-Stack Engineer · Product Creator
I'm a highly technical engineer with deep experience building complex systems across cloud infrastructure, native applications, real-time systems, 3D/VR platforms, and e-commerce integrations. I'm both an architect and hands-on developer, equally comfortable with backend internals, front-end polish, infrastructure, and commercial strategy.
My work spans from modern spatial computing on Apple Vision Pro to preserving vintage computing systems—and everything in between. I take ideas from sketch to production, properly built.
