Your dedicated cybersecurity partner

I'm an independent security consultant with 5+ years hands-on experience securing enterprises — 132+ clients and 140+ projects across penetration testing, application security, DevSecOps and GRC. I run engagements end-to-end, from scoping through executive readout.

On the academic side I'm a PhD scholar at IIT Bhilai, researching threat mitigation in cloud-native environments. The research informs the consulting and vice-versa — clients get the rigour of academic methodology with the velocity of an indie operator.

Independent means flexibility, direct senior attention, and pricing that actually makes sense for your budget — no agency overhead.
