About

I build systems that are secure by design — not patched after the fact. I am a Cybersecurity Engineer and M.Tech CSE candidate specializing in threat modeling, cryptographic protocols, and secure system architecture. I hold a Government of India Patent for an IoT-based encrypted monitoring system and have built real-world secure platforms including an AES-256 file sharing system and an AI surveillance system with 92.4% detection accuracy. Core Skills: Burp Suite · Wireshark · JWT · AES-256 · Zero Trust · OWASP · FastAPI · Python · Docker

Experience

Software Developer

Aerial Borne

3 mos · Gurugram, Haryana, India

Implemented JWT authentication and RBAC across all REST API endpoints enforcing least-privilege access. Conducted security review of APIs — identified and patched an input validation vulnerability preventing injection attacks. Enforced Secure SDLC practices including threat-aware design, secrets management, and CI/CD via GitHub Actions. Reduced development time by 30% using AI-assisted tools without compromising security standards

Security-Aware Software Developer Intern

Aerial Borne Bharat Pvt. Ltd.

Jun 2025 – Aug 2025

Implemented JWT-based authentication and RBAC across REST API endpoints; conducted an API security review and patched an input validation vulnerability; enforced Secure SDLC practices, secrets management, security-focused code reviews, and GitHub Actions CI/CD; used GitHub Copilot to reduce development time by approximately 30%.

Projects

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.
