About

I work across the full data lifecycle: automated ETL, analytical platforms, cloud architecture and agentic AI. Currently Data Strategy Analyst at Nestlé and wrapping up an MSc in Data Science & AI at UTEC (top 10%, ranked 2nd), after building market intelligence over 150M+ records in Peru's energy sector.

Outside the day job I ship real products end to end — an open observatory of medicine prices, agentic RAG over electricity contracts, a governed NASDAQ screener, computer vision for analog animation. Scraping, pipelines, databases, APIs, evaluation, and the product on top.
