What I'm looking for

I'm looking for remote opportunities in AI data annotation, data quality, quality assurance, or data analysis where I can apply rigorous validation, structured documentation, and Power BI reporting to improve reliable decision-making.

I've built AI data annotation and quality workflows through freelance projects, reviewing text and audio data for accuracy, consistency, completeness, and guideline compliance in Label Studio. I document quality issues, evaluate content objectively, and handle ambiguous cases using Human-in-the-Loop practices.

As a freelance data analyst, I clean and transform datasets with Excel and Power Query, build Power BI dashboards, and create DAX measures for sales, profit, and business performance. My earlier operations coordination work strengthened my reporting, inventory-control, quality-review, and team-coordination experience.
