## What I'm looking for

```text
I'm looking to build AI and data products where I can apply machine learning, NLP, RAG, analytics, and clear communication to solve practical problems.
```

## About

```text
I'm building AI-powered products at Auroria and Coutura, including a Colombian labor-law RAG system with PII anonymization, multi-provider LLM routing, and per-user AI cost controls. I also designed Coutura's recommendation feed and AI visual product search.

My work spans machine learning, deep learning, NLP, statistical analysis, and optimization. I turn data into actionable insight through dashboards and KPI tracking, and I've applied BETO, JAX, PyTorch, XGBoost, LightGBM, and RAG architectures to real projects.
