Engineering data systems that drive decisions

My path from Industrial Engineering to data engineering reflects a consistent focus on one thing: Building systems that make data reliable and useful. Currently, I design and maintain Python-based ETL pipelines and API validation workflows that ensure data integrity across healthcare platforms. In parallel, I design end-to-end data engineering projects, from a PostgreSQL data warehouse to a production-grade GCP stack with BigQuery, dbt, and GitHub Actions CI/CD. Applying data architecture, modeling and engineering to real datasets.

I target roles where engineering rigor and analytical thinking meet. Analytics Engineer, Data Engineer and Senior Data Analyst positions where clean pipelines, well-modeled data and business impact are equally valued.
