About me · by demonstration

Make, then describe.

Self-taught engineer from Caracas. I think in pixels, vectors and stack traces. Below, four things I made: three of them running right here in the page, and one concert hall rebuilt from a seating chart.

Self, segmented.

Click the portrait. A SAM2 decoder runs in your browser, fed by pre-encoded image embeddings — ONNX Runtime + WASM in a Web Worker, nothing leaves your tab. Same pattern I use to keep latency low and bills off the GPU rental.

Caracas

Where it started.

Born in Caracas in '96. First touched a computer in a smoke-filled cyber café between brownouts, and never let go.

Mind, mapped.

Twenty-eight things I work on, projected onto a plane and clustered by relation. Click any node — the card pins, related ideas connect, the rest dim. Same trick that powers RAG, search and the segmentation tile above: vectors do the heavy lifting, geometry does the explaining.

Stones, simulated.

Lumière — a jewellery configurator running live in this tile, from the same Expo codebase that ships to iOS and Android. Rings are composed from a head and a shank at runtime, so all 11,520 combinations render on demand instead of being pre-rendered. The stones are a hand-written shader: the gem’s geometry is baked to a cubemap once, then refracted with per-channel dispersion.

Halls, rebuilt.

Carnegie Hall’s Stern Auditorium, rebuilt from nothing but its public seating chart. The chart gave survey-accurate positions for 2,758 seats; everything above them is generated — nine Houdini builders for the columns, arches and doors, and a spec-driven ornament library that dresses four tier parapets. Nothing was sculpted by hand. Scroll the renders.
