Secure File Sharing System — End-to-End Encrypted Platform
Built a secure file-sharing system using AES-256 encryption for stored files, TLS for data in transit, SHA-256 integrity hashing, JWT authentication, RBAC, rate limiting, and strict input validation. Achieved 98% secure file handling accuracy and tested security edge cases including interrupted uploads, filename collision injection, empty file attacks, and token replay scenarios.
IoT Security System — Crop Monitoring Bracelet
Architected a wearable IoT security system with end-to-end encrypted MQTT communication between an edge sensor and cloud dashboard. Implemented anomaly detection, device-level validation, encrypted transmission, and server-side anomaly scoring. Recognized under Government of India IPR; patent published in 2025.
AI-Powered Surveillance Detection System
Built a real-time vehicle number plate detection and recognition system using YOLOv5, OpenCV, Tesseract OCR, and Python. Custom-trained the detection model to 92.4% accuracy and designed tamper-resistant output validation with integrity logging.
LeadBot Pro — Secure SaaS Application
Designed and deployed a security-first SaaS platform with HTTPS enforcement, strict CORS policies, environment-based secrets management, secure Razorpay payment integration, authentication, session management, API access controls, and encrypted MongoDB Atlas data at rest.
