Staff Engineer — AI Systems · Agent Orchestration · Platform Architecture
I build AI systems you can audit — evaluation gates, local LLMs, agent routing planes, MCP tool ecosystems. TypeScript · Python · Barcelona · L'Hospitalet de Llobregat.
Immersive artist hub: Three.js galaxy, music catalogue and narrative universe (Judas Era in four chapters). Public, verified.
- Repo: https://github.com/belentani7/belentani.es
- Stack: Next.js · Three.js · WebGL
- Demo: https://belentani.es (HTTP 200)
Zero-token skill router for Claude Code and Qwen Code. Public, verified.
- Repo: https://github.com/belentani7/meta-skill
- Stack: Python · TypeScript · CLI
- Demo: https://meta-skill-theta.vercel.app (HTTP 200)
Open campus for cybersecurity and responsible AI, anonymous enrolment, automated tests. Public, verified.
- Repo: https://github.com/belentani7/secure-t
- Stack: Next.js · TypeScript
- Demo: 398 HTML pages in the repository (git tree count, 2026-11-15)
GPU compute cost optimizer for diffusion pipelines, up to 70% savings. Public, verified.
- Repo: https://github.com/belentani7/gpu-cost-optimizer
- Stack: Python · ComfyUI · ML
- Demo: repository with documented execution
A galaxy of 200,000 particles in a single WebGL2 file: one draw call, no dependencies, no network requests. Built to answer a measurable question rather than an aesthetic one.
- Repo: https://github.com/belentani7/kepler
- Stack: WebGL2 · GLSL · Vanilla JS
- Demo: https://belentani7.github.io/kepler (HTTP 200)
- Measured: 200k particles at 59.9 fps, median frame 16.7 ms, p95 17.5 ms, 0.1 ms of CPU per frame on an Intel UHD 620. Ceiling is 280k at a solid 60 fps; above that the p95 degrades before the median does.
A linter for GitHub profile READMEs: dead links, missing alt text, remote assets and claims nobody can check. Standard library only, tested on three Python versions in CI.
- Repo: https://github.com/belentani7/profile-lint
- Stack: Python · CLI · GitHub Actions
- Usage:
profile-lint README.md --root . --links - Measured: 85 images without alt text across 7 profile READMEs belonging to accounts with 26,000 to 60,000 followers.
A system enters this list when its purpose is understandable, the public experience can be walked through, and the repository explains how to run and verify it. Ideas, prototypes and projects without that evidence stay out.
Private work is described but never counted as evidence: model evaluation guard, governance control plane and a registry of 311 installable skills for 7 CLI agents live in private repositories.
Every claim on this page links to a repository, a test or a measurement — or is labelled unverified.
- Engineering evidence: ./docs/engineering-evidence-2026-10-29.md — commit counts, review windows and the limits of what activity metrics measure.
- Profile archive: ./docs/profile-archive-2026-10-29.md — previous versions of this page.
- Product sheet: ./plataforma/FICHA.md — measured scope, stack and known gaps.
- Doctrine: ./BIBLIA.md — vision, mission, rules and design tokens.
- Living Machine: ./docs/living-machine/index.html — browser tools that run on repository files, with no upload; a local demo, not a verified live deployment.
- Proof: ./PROOF.md - what the page can prove, claim by claim, and what would falsify it.
Private, archived or experimental work stays out of this page.
Source and reproduction: scripts/profile_evidence.py runs nine machine checks and exits non-zero
on drift. The same checks run in CI on every push.

No third-party stats widgets, no visitor counters, no external tracking images. One local SVG cover; everything else is text and local links.
Browser tools that run on the repository files of this repo, uploading nothing: image conversion, subtitles, CV reading, palette extraction.
This showcase is a local demo over repository files: not a verified live deployment. Some pieces stay private, archived or experimental and are deliberately excluded from the public catalogue.
