As a Data Scientist with a Bachelor’s in Statistics from the University of South Florida and an advanced Data Science & Machine Learning certification from MIT (2024), I transform complex datasets into actionable insights for business impact. I specialize in Python (Pandas, NumPy, Matplotlib, Seaborn), R, and machine learning techniques like regression, decision trees, and clustering, with a proven track record in predictive modeling and exploratory data analysis (EDA). Currently, I’m sharpening my SQL skills (SQL Associate Certification in progress) to complement my expertise. My projects showcase real-world results: I built an Amazon recommendation system with an RMSE of 0.88 using collaborative filtering and optimized a lead conversion model for an EdTech startup, achieving 83% accuracy and boosting marketing efficiency by 15%. With experience as a Patient File Coordinator, I bring precision and process optimization, reducing retrieval times by 20% while maintaining 99% accuracy. Open to Data Scientist or Data Analyst roles in tech startups, finance, healthcare, or cybersecurity, I’m a U.S. citizen flexible to relocate or work remotely. Let’s drive data-driven innovation together.
