What I'm looking for

I seek a leadership role where I can drive enterprise AppSec and cloud-native security programs, mentor teams, and deliver measurable risk reduction and secure-by-design outcomes.

I am a technology-driven IT leader with over 19 years of experience, currently serving as a Principal Application Security Engineer focused on enterprise security risk management and secure SDLC adoption.

I have led global AppSec and DevSecOps strategy, embedding Secure SDLC to reduce enterprise-wide vulnerabilities by 70% and systemic risk by 60% while orchestrating vulnerability lifecycle automation to cut MTTR by 45%.

I architect cloud-native Zero-Trust solutions across AWS and OCI, hardened APIs and containers to shrink the attack surface by 60%, and engineered AI security guardrails to prevent injection attacks and PII leaks, maintaining compliance with global data privacy standards.

I build governance and operational frameworks — OSS governance, GRC, Threat Modeling, SAST/DAST/OSS optimization, RASP/WAF/Splunk AppSec logging — and have led global teams of 100+ to deliver measurable security outcomes and resilient business continuity.
