About

Full-stack developer at NeuralGT, where I build Fintrack, a personal finance SaaS for the Chilean market (FastAPI + PostgreSQL + Next.js).

On the side, I am transitioning into Machine Learning Engineering: shipping production-grade ML projects, studying graduate-level statistics and optimization, and aiming for a remote ML role by late 2026.

Recent CS graduate (UTH 2026, 97/100 GPA).

Featured Project

geoplay-recommender

Geo-contextual player segmentation & content ranking

Production-grade ML pipeline simulating a Pokémon GO–style game with 50,000 synthetic players, 162M events, and 5 behavioral archetypes (commuter, casual evening, weekend explorer, hardcore raider, lunch player). The pipeline clusters players via HDBSCAN on a 54-feature matrix (temporal density, H3 spatial footprint, session behavior) and ranks content with LightGBM.

Highlights

• Partition-streaming feature pipeline bounded to ~3 GB constant memory on 162M events
• 54 engineered features across three families: temporal (39), spatial with H3 (7), behavioral (8)
• Strict tooling: uv, ruff, mypy, pre-commit hooks
• MLflow experiment tracking, FastAPI serving layer, Dockerized deployment, GitHub Actions CI/CD

Currently Focused On

• Shipping geoplay-recommender end-to-end: clustering → ranking → MLflow → FastAPI → Docker
• Strengthening statistics and optimization fundamentals for graduate-level ML work
• Building fluent technical English for international remote collaboration

When I'm not coding, I write literary fiction (currently a novella anchored in Camus and Kierkegaard), explore FromSoftware games, and overthink internet culture.

Find Me on the Field

A small Yanma to close. Field guide entry: Bug/Flying type, Generation II, Pokédex #193. Known for its compound eyes that see 360° around itself a useful trait for someone who works with data from many angles :D
