What I'm looking for

I'm looking to solve complex technical challenges through scalable AWS data platforms and reliable Python software, while providing technical leadership in collaborative teams that value strong engineering practices, automation, and teamwork.

At Bluetab, an IBM Company, I optimize AWS ELT workflows and automate failure recovery, removing around 15 hours of manual Python intervention each month. I architect and maintain robust Airflow data pipelines from diverse sources for analytics and business intelligence.

Previously, I delivered near-real-time AWS data pipelines for a major digital sports property company, built a GDPR-compliant email-modification system around a Python state machine, and developed production-grade APIs and distributed systems. At DataFactory TIC and Airbus, I led cloud data initiatives, built ETL/ELT pipelines, and improved cavitation-event detection threefold through statistical analysis.
