About Me

Cyber security foundation.
Full-stack execution. AI-native thinking.

I've been building, breaking, and securing systems since I was 10 — starting with hardware repairs, progressing through exploit development and network forensics, and now architecting production-grade AI platforms and enterprise automation systems.

Formally trained in Cyber Security & Digital Forensics at Middlesex University London — covering everything from memory forensics and malware reverse engineering to blockchain analytics and AI/ML systems. Now based in Kerala, building for clients across the UK, GCC, and India.

From enterprise certificate platforms processing 700+ documents daily with QR validation, to AI fleet management copilots with hybrid RAG architecture, to cross-border commerce engines with escrow infrastructure — I ship systems that handle real money, real users, and real complexity.
