๐Ÿ“Š Business Analysis | Data Analytics | NLP & Pattern Detection

I'm a BBA graduate in Data Science and Artificial Intelligence who works at the intersection of business understanding and technical analysis. I build end-to-end data pipelines, statistical models, and analytical frameworks โ€” and translate what the data says into decisions that actually get made.

๐Ÿ“ Targeting Business Analyst and Data Analyst roles โ€” focused on SQL, pattern detection, and NLP-based classification ๐Ÿ“ˆ Currently building expertise in business analysis (ECBA), Trust & Safety analytics, and statistical investigation


๐Ÿง  Core Skills


๐Ÿ“š Currently Learning


๐Ÿ› ๏ธ Tools & Workflow


๐Ÿš€ Featured Projects

Project Description Tech Stack
๐Ÿง  Heart Rate vs. Temperature โ€” 6-Month Pattern Detection Study Longitudinal physiological analysis fusing Apple Watch data with OpenWeatherMap API. Applied Random Forest, ARIMA, ANOVA, and time-lagged correlation across 6 participants. Null result at population level โ€” individual variability (P3 outlier) isolated and reported. Python, Random Forest, ARIMA, OpenWeatherMap API, Apple HealthKit XML
๐Ÿงฎ Customer Churn Prediction System End-to-end churn prediction system with Streamlit web app, model explainability (SHAP), and risk segmentation. Python, XGBoost, SHAP, Streamlit
๐Ÿš• NYC Taxi Demand Forecasting + Weather Impact Analysis Time-series forecasting with XGBoost and weather data integration, with Power BI dashboard for demand and pricing insights. Python, XGBoost, Power BI
๐Ÿช Store Uptime Analytics API FastAPI backend generating uptime/downtime reports from raw store activity logs. FastAPI, Pandas, Uvicorn

๐Ÿ”ฅ Highlights

  • ๐Ÿง  Built 6-month multi-source data pipeline fusing wearable physiological data with environmental API feeds
  • ๐Ÿ“Š Applied Random Forest, ARIMA, ANOVA, and T-tests on real-world longitudinal datasets
  • ๐Ÿ” Conducted anomaly detection and root cause analysis in live operational environments
  • ๐Ÿงฎ Deployed Churn Prediction Web App with XGBoost & SHAP explainability
  • ๐Ÿ“ˆ Built time-series forecasting models with <6 RMSE on real-world data
  • ๐Ÿ“Š Created interactive BI dashboards for business reporting and stakeholder decision-making

๐Ÿ” What I'm Exploring
