What I'm looking for

I'm seeking remote Data Engineer positions in international product teams.

At Triskin Data Agrin, I orchestrate API ingestion pipelines with Airflow and Docker using a Bronze, Silver, and Gold Medallion architecture. This work supports error traceability, automated governance, and self-service analytics in Apache Superset.

I also manage PostgreSQL and AWS data environments, processing spatial and relational datasets with Python. I led cloud environment migrations and refactored legacy queries to reduce database infrastructure and maintenance costs.

Previously, at Uber, I consolidated delivery operations data across MySQL, Presto, and Hive to help detect churn-prone and offending clients and reduce operational costs. I also built KPI dashboards and automated reporting workflows; at Direção e Sentido, I built ETL pipelines and designed analytical SQL queries for operational reports.
