AI Software Developer · Physicist · Catalonia
Physics rigor, applied to systems
that need to actually work.
I'm Guillem Barta González. Trained as a physicist, now building AI systems for robotics — currently migrating a production companion-robot platform to a multi-agent architecture on Azure AI Foundry. When I'm not at a keyboard, I'm usually on a ridge, a bike, or a lake.
01 — About
I like problems with edges.
I'm a physicist with a master's in Artificial Intelligence from Universitat Internacional de Valencia. During my physics studies I interned at FlexSim, completed an ERASMUS semester in Norway, and built a single-pixel camera prototype for my bachelor's thesis in the Wavefront Engineering Lab at Universitat de Barcelona.
I'm currently a Software Developer at Group Saltó's R&D department, implementing AI functionalities for companion robots — wake-word spotting, speaker recognition, and the backend APIs that tie it all together. Right now that means migrating our bot platform, which serves elderly users across a physical robot, a web client, and voice, off a legacy dialog framework and onto a modern multi-agent architecture.

Selected work
A few things I've built — from production AI at work to research and personal projects.
AI for companion robots
End-to-end AI on the robotics R&D team: personalized wake-word spotting models deployed to Android, speaker recognition with user-management views, and a Semantic Kernel API deployed as a web service.
Single-pixel imaging camera
Built a single-pixel camera from a commercial projector and a Raspberry Pi in the Wavefront Engineering Lab, studying how illumination-system position affects image contrast.

Industrial digital-twin logic in FlexSim, with a Python connectivity module used to train neural networks to pick the most efficient sequence of objects and plan warehouse routes.

Same ridge, different kind of climbing.
- Mountain hiking
- Climbing
- Downhill cycling
- Alpine skiing
- Backcountry skiing
Mostly around the Pyrenees. If you've got route recommendations, that's a good reason to reach out too.
