Final-year B.Tech CSE student at VIT Chennai, specializing in cybersecurity. I architect production systems that don't just function they resist.
I've spent the last two years operating at the boundary between security and infrastructure engineering. My work on VISTA a live production system serving 1,500+ users taught me that real security isn't a checklist; it's a mindset baked into every architectural decision.
From SSH key-only authentication and IP whitelisting to automated threat monitoring and disaster recovery, I build systems that assume they're under attack and prove otherwise.
I'm drawn to environments where security is a first-class engineering concern GCCs, product companies, and security teams that treat infrastructure as a battleground, not a utility.

Built Python-based security automation for real-time threat monitoring, automated backups, and disaster recovery systems.
Maintained 90% uptime through proactive patch management and system hardening.
Cybersecurity Intern
Genzeon
Conducted penetration testing and vulnerability assessments on production web applications, delivering actionable remediation reports.
Configured Azure Sentinel SIEM with custom analytics rules for real-time threat detection across cloud infrastructure.
Improved Mean Time to Detect (MTTD) by implementing a centralized log aggregation strategy across distributed systems.
VISTA
Production security ownership of a live 1,500+ user system
VISTA is VIT Chennai's capstone project management platform but treating it as just another academic project misses the point. What matters is that I owned the entire security and infrastructure posture of a live system serving over 1,500 active users for over a year.
This wasn't a lab exercise. Every decision had real consequences: a misconfigured firewall meant students couldn't submit work; a vulnerability meant their data was exposed. That pressure shaped every choice I made.
