What I'm looking for

I seek a data-engineering role where I can build reliable ETL pipelines, improve data quality, collaborate cross-functionally, and continue learning in a remote-friendly, growth-oriented environment.

I am a detail-oriented Data Engineer with a proven track record of optimizing data pipelines, automating ETL processes, and ensuring high-quality data delivery. I develop modular, testable Python solutions and design performant SQL models using platforms like Snowflake, Redshift, and Databricks.

My background includes building Airflow DAGs, PySpark data platforms, and Lakehouse architectures while working remotely across several companies. I have experience in QA/SDET testing, data validation, and deploying reliable data ingestion pipelines that support analytics and product teams.

I bring strong analytical thinking, problem-solving, and cross-functional collaboration from roles in data engineering, teaching, and project management, and I continuously pursue certifications and advanced education to keep skills current.
