Tools
Node.js Express SQLite
- Full-stack attendance platform with role-based access across 18 REST endpoints
- Secured auth endpoints with bcrypt password hashing and token-based session validation
- Normalized SQLite schema with 4 linked tables and foreign-key constraints
- Automated attendance logging with photo capture, geolocation tagging, and late-arrival detection
- Task tracking with 3-tier priority levels, CSV export, and admin database backups
Python MySQL LightGBM
- Simulated a 150K-transaction UPI dataset modeling normal and fraud behavior patterns
- Engineered 19 behavioral features per user window (device-switch ratio, night-transaction ratio, etc.)
- Trained a LightGBM classifier achieving 0.844 ROC-AUC and 88% accuracy on imbalanced data
- Tuned decision threshold to hit 98% fraud recall at 85% precision
Node.js Express.js Socket.IO
- Real-time code editor supporting 5 concurrent users via Socket.IO broadcast sync
- Live multi-user cursors with color-coded, auto-fading labels, plus in-room chat
- Integrated JDoodle API to execute code in C++, Java, and Python3 with custom stdin
- Built an AST visualizer with Tree-sitter for interactive C/C++ structure analysis
Python OpenCV Mediapipe
- Real-time computer vision system converting hand gestures into text
- Extracted hand landmark features with preprocessing for consistent gesture recognition
- Improved model accuracy through iterative testing and gesture-mapping refinement
