Works

Execution across backend, AIoT, products, and research.

This is where delivery becomes concrete: production systems, ventures, research, and selected solution work shaped from a backend, platform, and applied AI perspective.

Professional Experience

Roles where platform thinking, edge-to-cloud delivery, and applied AI execution were part of the day-to-day work.

Role: Architecture, integrations, and shipping

Guilherme has other UIs, marketing sites, and web apps that are not listed openly in this portfolio and sit outside the storyline he is leaning into right now. He does not name or link them here: his public focus is platform, backend, and applied AI, not collecting front-end showcase pieces.

Scope: Additional UIs, sites, and web apps, outside the current public focus

Names, brands, and public URLs are intentionally out of this cut, not a statement of inactivity.
