What I'm looking for

I seek roles focused on end-to-end automation and data quality in analytics-driven products, with opportunities to lead test strategy, integrate CI/CD quality gates, and work on large-scale ETL and BI validation.

I am a Data & Analytics-focused Quality Engineer with 7+ years designing and scaling automation and data validation frameworks across enterprise platforms, ensuring data integrity and reliable analytics. I specialize in SQL-based reconciliation, ETL and data pipeline testing, API and UI automation, and validating BI dashboards to support data-driven decision-making.

I have led technical test strategy and framework standards for customer-facing and financial systems at enterprise companies, building Java/Selenium automation, REST Assured API suites, and large-scale data reconciliations on Snowflake and SSMS. I bring a product-oriented mindset, CI/CD integration experience, and a focus on prevention of regressions in analytics and AI/ML-adjacent systems.
