What I'm looking for

I seek a collaborative role combining data analysis and QA where I can build dashboards, automate reporting, and influence product decisions while growing technical and leadership skills.

I am an analytical Data and QA specialist with 5+ years of experience building measurement frameworks, dashboards, and QA processes to improve product quality and customer experience. I partner with stakeholders to turn complex data into actionable recommendations.

I design and deploy ETL workflows, write SQL and Python for data validation and analysis, and create executive Tableau dashboards. My work reduced manual reporting effort by 40%, improved reporting accuracy by 15%, and produced multiple executive-level dashboards.

I combine rigorous QA testing with BI reporting to ensure data integrity and business alignment, presenting findings to leadership and documenting measurement frameworks and data dictionaries. I prioritize clear data storytelling, process automation, and cross-functional collaboration to drive measurable operational improvements.
