Projects
End-to-end data & AI systems — from web-scraped chaos to governed lakehouses, live dashboards, and autonomous agents.
Airbnb Market Insight
A Medallion lakehouse that scrapes the Guatemala City short-term rental market, refines it Bronze → Silver → Gold on Delta Lake, and serves a live Next.js dashboard straight from Cloudflare R2.
AI Co-Host Agent
A LangGraph state machine with a human-in-the-loop validation step that answers guest messages autonomously across WhatsApp and Gmail — replacing co-host fees.
RAG Training Ground
Mines historical hosting conversations through the lakehouse into a vector library, teaching the agent to answer guests in my own voice.
Credit Risk Scoring
A behavioral scoring model on a Databricks Medallion lakehouse that identified the top default drivers and cut non-performing loans 32% within six months.
