Vectron
A public, navigable 3D map of meaning: 20,473 real concepts embedded with bge-m3 (Workers AI) in 1,024 dimensions and projected to 3D via PCA, rendered in WebGPU with Three.js. It grew out of the AI courses Esteban teaches every month, so the audience can see an LLM's semantic space instead of imagining it — and it explicitly measures where the projection lies instead of hiding it.
Cereza

It offers solutions to simplify administrative processes, manage employee performance and development, talent attraction, training and development, asset management, and organizational climate.
