About
Economics

Universitat Jaume I
My purpose in life is to give back to society everything it has given me by making a positive contribution to the world, creating impact and inspiring others, while caring about the future of human beings both individually and collectively.
I have always been connected to technology. When I was younger, I was obsessed with understanding how smartphones worked. I compared devices, watched tech channels like Topes de Gama on YouTube, and by the age of 12 I was already exploring iPhone and iPod Touch hacking to install customizations and apps outside the App Store.

Projects
100vibecoding.com
A platform to become AI-native by building real projects with natural language.
formcheck
Detects graders that reward the form of a solution rather than its behaviour: 22.2% of controlled SWE-bench Verified tasks reject a behaviour-preserving rename of a symbol the gold patch touches.
aya-act
Teaches multi-step agentic tool use (chaining, refusal and branching) to a small on-device model by distilling teacher trajectories through a strict verifier.
PipeIQ
Operational copilot for a U.S. water utility, replicating a system built on Palantir Foundry/AIP: an LLM infers pipe material from illegible records and cites its evidence, and deterministic arithmetic scores the risk.
ZeroCompute
Chat that runs the model inside the browser on WebGPU with weights cached in OPFS, falling back to an Edge route when local inference is unavailable.
stif.works
AI-powered client-professional matching platform.
safe-openai-streaming
Open-source library that hardens OpenAI streaming against truncated SSE events, malformed payloads, and mid-stream network failures.
Phoenix
RunPod Community Cloud supervisor that auto-checkpoints training, replaces dead GPU pods with the cheapest available option, and resumes runs.
LineTS
Unofficial, self-hosted TypeScript agent runtime inspired by Cartesia's Line model, built on the official SDK.
microstructure-alpha
Quantitative mean reversion strategy built from market microstructure insights.
Things That Don't Scale
Dape
Platform that collected opinions to help companies shape their products.
I manually collected feedback, converted it into PDFs by hand, analyzed it myself, and sold it.
