DATA ENGINEER · AI & MACHINE LEARNING

I build data pipelines & AI that scale.

3+ years building ETL/ELT pipelines and data platforms on the cloud — and the machine learning and AI layer that runs on top of them.

I'm a Data Engineer with 3+ years building ETL/ELT pipelines and data platforms, focused on AI and machine learning in production. Most of my work lives on Google Cloud — ingesting from APIs and the open web, landing it in BigQuery, modeling it with dbt, orchestrating it with Airflow, streaming it through Kafka, and packaging everything in Docker so it runs the same everywhere.

On top of that foundation I ship the ML and AI layer: training and serving models, sentiment analysis pipelines, and LangChain agents and RAG systems wired into real databases and APIs.

I've delivered for remote teams across the United States, Australia, Spain, Mexico, Chile and Argentina — building data infrastructure and leading analytics projects end to end.
