TCS (Tata Consultancy Services)

01 — Bio

Currently in the onboarding / pre-joining phase at TCS, preparing for the internal assessments required before joining, and working toward the CSP (Cyber Security Professional) designation.

My interest sits on both sides of the fence — defensive fundamentals (CIA triad, network security, secure architecture) and offensive security (CTFs, injection attacks, exploitation). I'd rather understand an attack by reproducing it than by reading about it.

Outside of coursework, I build small security-oriented tools — most recently an AI-assisted penetration testing assistant that chains recon, CVE correlation, and LLM-based vulnerability triage into a single workflow.
