What I'm looking for

I’m looking for a role where I can own end-to-end data pipelines—using dbt, SQL, Python, and orchestration—to automate quality checks, improve reliability, and collaborate across engineering and analytics while mentoring others.

I’m a Senior Data Engineer with 10+ years of experience building and maintaining reliable data pipelines, ELT/ETL frameworks, and data quality systems across banking and sports betting.

I’m technically grounded in dbt, SQL, and Python, and I focus on end-to-end reliability: from modeling and warehousing to validation, automated testing, and infrastructure maintenance. I bring a pragmatic, continuous-improvement mindset—always looking for ways to do things better, not just faster.

In recent roles, I maintained and optimized legacy pipelines (including dbt, DB2, and Prefect) to ensure business continuity for critical banking operations. I designed comprehensive data quality frameworks with automated tests and validation checkpoints, reducing downstream errors by ensuring only qualified data reached analytical models.

I also deliver hands-on solutions for data teams—engineering dbt models across multiple business units, developing Python automation scripts for validation checks, and configuring orchestration to execute SQL tests across sources and layers. I value clear communication and cross-functional collaboration, and I enjoy mentoring colleagues while supporting on-call operations to resolve time-sensitive production issues.
