🔐 Quantum-Secure Video Conferencing

B.Tech Project (BTP) — Post-Quantum Cryptography

Quantum-resistant real-time video conferencing using NIST-standardized PQC algorithms. Kyber-768 for key exchange, Dilithium2 for signatures, AES-256 over SRTP for media — <1ms crypto overhead at 30 FPS.

🌐 Interactive Terminal Portfolio

Web Development — Serverless Architecture

A portfolio that looks and works like a real terminal CLI. Type about, projects, skills to navigate. Features live CP stats fetched via Netlify Functions, a browser-based Cipher Machine, and a secure contact form — zero backend servers.

🏛️ Blockchain Asset Registry & Trade Platform

Distributed Ledger · Smart Contracts

A permissioned blockchain platform for registering and trading real-world assets. Built on a private multi-node blockchain with QBFT consensus — supports asset tokenization, ownership transfer, and trade lifecycle management via smart contracts.

🔑 MPC Wallet — Split-Key Architecture

Cryptography · Cold Storage · Key Management

A threshold-based crypto wallet splitting the private key between a hot machine and a cold machine using MPC. Neither machine alone can sign a transaction — both must participate, ensuring the full key never exists in one place.
