What I'm looking for

I'm looking to apply my QA, application security, DevSecOps, and detection engineering experience to build secure products, automate security controls, and strengthen threat detection and incident response.

At HCL Technologies, I tested Microsoft Teams, SharePoint, and Microsoft Copilot, designing 200+ functional, regression, and exploratory test cases. I also logged and triaged 300+ defects in Azure DevOps and improved defect-verification turnaround by 22%.

I bring accessibility and security into testing through WCAG 2.1 and Section 508 audits, secure SDLC practices, and OWASP Top 10-aligned scenarios for input validation, session management, and access control. My accessibility audits improved compliance scores by 30%.

Through Expadox Lab projects, I've built DevSecOps pipelines with SAST, DAST, SCA, and secrets scanning; authored Wazuh detection rules; automated SOAR remediation playbooks; and deployed an adversarial AI threat-detection service using XGBoost, PyTorch, FastAPI, and Docker.
