Engel Mandujano · Senior Technical Program Manager

HW/SW programs at Bosch · AI adoption · Building products end-to-end

I'm Engel. Most of the projects here are love/passion/curiosity-driven.

I studied Mechanical-Industrial Management Engineering; code became my second workshop. That degree taught me to think in systems, processes and bottlenecks, which is exactly how I approach software projects.

Passionate about: art, ballet, music, AI, business and people.

Tools I've built with

I'm not a software engineer. I've built enough with these tools to know what each one does, how they fit together and where projects get stuck. That's what I bring to a team as a Technical Program Manager.
