🚀 Projects

🔍 CrimeCast: Crime Category Prediction

Python Scikit-learn Pandas NumPy Matplotlib Seaborn

  • Trained 4 classifiers (Random Forest, SVC, AdaBoost, Decision Tree) on LAPD crime data — Random Forest was the best performer
  • Engineered time-based, geographic, and demographic features; applied GridSearchCV hyperparameter tuning
  • Conducted feature importance analysis to identify key predictors across location, timing, and incident type

🔧 MLOps Pipeline: Explainability, Fairness & Drift Monitoring

MLflow SHAP GitHub Actions Scikit-learn Evidently

  • Built an end-to-end ML observability pipeline with SHAP explainability across demographic groups and data drift detection (KS, PSI tests) triggering automated retraining alerts
  • Automated the full pipeline (train → evaluate → explain → monitor) via GitHub Actions CI, cutting manual intervention to zero
  • Integrated MLflow for experiment tracking, model registry, and reproducibility

🌐 Student Management System – REST API

FastAPI SQLite JWT SQLModel Uvicorn Railway

A production-deployed REST API for managing students, courses, enrollments, and grades with JWT-based authentication.

  • Built full CRUD routes for Students, Courses, Enrollments, and Grades using FastAPI with auto-generated Swagger docs at /docs
  • Implemented JWT authentication (python-jose + passlib/bcrypt) — all routes are protected and require a valid token
  • Used SQLModel (Pydantic + SQLAlchemy) for ORM, with duplicate checks for emails, course codes, and enrollments; marks validated between 0–100
  • Deployed live on Railway with a Procfile + Uvicorn ASGI server

📊 Business Data Management – 99 Market Mall Case Study

Python SQL Pandas Matplotlib Tableau Excel

  • Analyzed sales and inventory data for a retail mall (~₹2,00,000/month revenue) to identify operational gaps
  • Identified top product categories contributing ~70% of total sales via Pareto analysis; surfaced seasonal trends (November peak, January low)
  • Delivered 6 actionable recommendations projected to reduce capital blockage by 20–25%

🧠 Quiz Master V1 & V2 – Full Stack Web App

Flask Vue.js Redis Celery SQLite Bootstrap

  • Built a multi-role quiz platform (V1) with admin and user roles, quiz creation, scoring, and result analytics
  • Extended to V2 with REST API, Vue.js frontend, Celery background jobs, and interactive performance dashboards
