David De Santiago — engineering with great responsibility

LinkedIn Email Open to roles

UC San Diego student building reliable software across product, infrastructure, and hardware boundaries.

Engineering power set: build, harden, and support

I turn practical problems into usable systems, then test the edge cases, document the boundaries, and make the result easier for the next person to operate. If something is a prototype, simulator, or planned integration, I say so.
