What I'm looking for

I'm open to international ETL and data warehouse testing opportunities where I can automate data validation, improve quality for complex data platforms, and collaborate with global teams.

I'm currently spearheading ETL/DWH testing for Nomura’s UK market abuse surveillance platform at Matrix USA, protecting regulatory data accuracy across SIT and Production. I built a Python testing framework and delivered 700+ automated Cucumber tests through Jenkins CI/CD pipelines, reducing UAT defect leakage by approximately 30%.

Previously, I led ETL validation across eight ANZ Bank projects at HCLTech and owned data lake migration testing for Transamerica at Apexon. Across banking, healthcare, and insurance clients, I validate complex data mappings, automate checks with Python and SQL, and collaborate effectively with distributed teams.
