About

Nicolás's stack leads with the visual side: Three.js, React Three Fiber and WebGL for 3D worlds, Phaser for browser games, and three-vrm for this avatar, all on React and TypeScript, where his production depth is 5+ years. Backend is a capability he integrates, not his lane: he knows and can wire Supabase, SQL, auth, Docker and some Kubernetes, plus Node on game servers, and Python where a project needs it, like the e-translator document pipeline. The lane he is moving into is visual and interactive work.

When a model is part of the experience, as in this talking avatar or in Doubland's AI Doubles, Nicolás builds the system around it rather than a one-shot prompt wrapper: explicit contracts, validation, retries, and failure states, so the experience survives production instead of collapsing on the first odd input.
