• Project 1 Predictive Maintenance for Bike Sharing — Links: [Backend] [Frontend]
• Developed a system that predicts when specific components of a bike are likely to fail.
• Built with Python, FastAPI, Scikit-learn, XGBoost.
• Synthetic ride data generation for training the ML model, and used PostgreSQL for structured data storage.
• React.js, Mapbox API for interactive dashboards, and route visualization.
• DVC, Git for version control & data tracking and CI with MLOps for reproducibility and automation.
• Model evaluation using cross val score and StratifiedKFold; Hyperparameter tuning optimized via Optuna.
• Project 2 AI Powered Adaptive Traffic Signal Control with DQN & SUMO — Links: [Backend] [Frontend]
• Developed a Deep Q-Learning agent that actively controls traffic signals based on lane queue lengths and waiting times.
• Achieved an 80.15% improvement over the traditional fixed-timer traffic controller!.
• Tech Stack: used Python, PyTorch, SUMO, TraCI, FastAPI. React.js.
• Results: End-to-end real-time simulation → RL agent → API → Live UI.
