What I'm looking for

I’m looking for a role where I can own data quality end-to-end—leading audits, enforcing compliance, and improving accuracy and workflow consistency—while collaborating with teams that value measurable outcomes, fast problem-solving, and continuous learning.

I’m a Data Quality Assurance Specialist with a strong background in data stewardship, promoted from Data Steward in October 2024 after consistently delivering top-tier productivity and quality results. I currently oversee data stewardship operations, ensuring data accuracy, compliance, and workflow consistency for work across defined quality standards.

In my role as Data Quality Controller, I manage a team of 11 data stewards and maintain high-quality standards through regular audits that verify data accuracy and completeness per project requirements. I developed guides to improve met accuracy and efficiency, successfully handled urgent tasks under tight deadlines, and built additional capability through my work as an AI Trainer and my data analysis upskilling with MS Excel, SQL, and recognized learning programs.
