Analytics Engineer and Data Engineer with strong data science background, building scalable pipelines and models.
What I'm looking for
I am an Analytics Engineer and Data Engineer with a strong foundation as a Senior Data Scientist, focused on designing robust, scalable data pipelines and models that drive business impact.
Throughout my career I have delivered end-to-end solutions across finance, retail, healthcare, and agribusiness, improving ML performance, data quality, and operational efficiency.
Notable achievements include implementing a Medallion Architecture that improved ML performance by 50%, consolidating dashboards via star schemas to reduce memory usage by ~60%, and building data validation with Great Expectations to block incorrect ingestion.
I prioritize data reliability, collaboration with cross-functional teams, and automating workflows (dbt, Airflow, CI/CD) to accelerate feature delivery and enable data-driven decisions.
