About

Final-year Computer Engineering (Ingeniero Civil Informático) student in Valparaíso, Chile, working across data science, machine learning and applied AI.

I don't just doubt a model's output — I translate that doubt into architecture. I build models (local and analytical), analyze data, and ground systems in real documentation so they don't hallucinate. I'm a full engineer, comfortable shipping software end to end, but my center of gravity is data and models.

What I do best: enter a field I don't yet know, learn it in depth, and ship a finished, deployed system that works inside it — and I know when to kill a project that no longer makes sense.

Currently: final-year capstone (AeroFit) · an independent research line in AI + quantum computing for drug discovery (literature-review stage).

Open to Data Scientist · AI/ML Engineer · Applied Scientist roles — 2026–2027, Chile or abroad.


Featured work

Project What it does Stack Links
AeroFit 🔒 Source-grounded AI that decides whether a pilot is fit to fly — a traceable, cited verdict, not a black box. 0.65 recall on the risk class. Python · RAG · Ollama · scikit-learn Case study · Live
PharmIQ 🔒 Pharmacy platform in daily use by a pharmacist: AI shift planning, expiry-controlled inventory and a MINSAL-grounded RAG assistant that cites its sources. Next.js · RAG · MINSAL Case study · Live
SincroAI 🔒 A no-code AI assistant that cuts SME admin work by ~40% with Gemini-orchestrated flows. Next.js · Gemini · No-code Case study · Live
B.L.A.S.T. 🔒 A YouTube-scraping intelligence engine that mines Starter Story success cases against LATAM pain points to surface validated business ideas. Python · FastAPI · yt-dlp · Gemini Case study · Live
Medical-Aeronautic RAG Engine The open dual-engine core (air-gapped RAG + ML) behind AeroFit — recall-tuned over public regulation. Python · RAG · Ollama · scikit-learn Repo
VR Chemistry Lab (3DLAB) Immersive Unity 6 / Meta Quest training lab so first-year students practice safely before the real lab. Delivered; ~15 users. Unity · C# · Meta Quest Repo
GreatSpades Python pipeline that recolors 8192² voxel-soldier textures while preserving fabric detail — tooling for a voxel game in development. Python · NumPy · Pillow Repo
