About Me

Hi, I'm Jay Thakur — a Data Analyst with a passion for transforming raw data into actionable insights. With a Master's in Data Science and hands-on experience across finance, e-commerce, and AI, I specialize in Python, SQL, and Power BI to solve real-world problems.

What I Do Best

✓ Data Storytelling: Turn complex analyses into clear business recommendations (like my NYSE Stock Analysis project)
✓ Full-Cycle Analytics: From cleaning messy data (Titanic Dataset) to building ML models (Lead Scoring System)
✓ Impact-Driven: Boosted dataset reliability by 40% at Sigma AI Data through precise annotation
✓ Technical Toolkit: Python (Pandas, Scikit-learn), SQL, Power BI, Tableau, and statistical modeling

My Approach

I believe data should solve problems, not just sit in spreadsheets. Whether optimizing marketing campaigns or identifying countries needing humanitarian aid, I focus on delivering actionable results.
