What I'm looking for

I seek a role where I can own QA and data-quality for e-commerce or AI products, work cross-functionally, drive measurable defect reduction, and grow into automation and data-quality leadership.

I am a QA Engineer with 4+ years of experience in software testing, e-commerce platforms, and AI-adjacent data quality work, experienced in fast-moving startup environments requiring broad ownership across quality, data, and operational processes.

I have hands-on experience in manual and API testing, dataset preparation, labeling and annotation, SQL auditing, and validating AI-assisted product content and catalog workflows to improve reliability and reduce defects.

I have driven measurable impact—reducing checkout and catalog-related defects by ~20% and recurring production issues by 15%—and I prioritize data-driven validation, clear defect documentation, and cross-functional collaboration to maintain product quality.
