Description

My career started in Quality Assurance, expanded into development, and naturally evolved into a role at the intersection of software reliability and offensive security. Today, I work across both sides of the Software Assurance spectrum: preventing defects and vulnerabilities, and identifying them before they can be exploited.

On the defensive side, I design and maintain robust test automation frameworks to improve reliability, reduce regressions, and support confident releases. On the offensive side, I perform security analysis and penetration-style assessments, helping teams understand real-world risks beyond surface-level scan results.

This combined perspective allows me to deliver pragmatic, risk-focused insights that improve both software quality and security posture.
