IV —About

Security-first
thinking, applied.

I started coding as a teenager — tinkering with hardware, writing scripts, and figuring out how things break. That curiosity led me to study Cyber Security & Digital Forensics at Middlesex University London, and it shapes how I approach every project today.

I hold a Diploma of Higher Education (DipHE) in Cyber Security & Digital Forensics from Middlesex University London (Sep 20222024), where I studied memory forensics, malware analysis, network security, cryptography, and secure software development. That security foundation shapes how I build everything least-privilege access, audit trails, hardened infrastructure, and encrypted-by-default are not afterthoughts in my work, they're the starting point.

Now based in Kerala, I build for clients across the UK, GCC, India. From an enterprise certificate platform managing 1,500+ certificates for a Kuwait-based HSE training company, to a multi-tenant compliance SaaS for the GCC market, to AI fleet management copilots I ship systems that handle real users and real complexity.
