Built a Playwright-based scanner that detects OWASP Top 10 vulnerabilities across web assets automatically — drove a 40% reduction in critical vulnerabilities.

Integrated security review into the SDLC pipeline so vulnerabilities are caught before reaching production; partnered with dev teams on remediation of critical and high-severity issues.

Architected API security testing strategies against OWASP Top 10 and OWASP API Security Top 10; wrote PoC exploits to demonstrate risk and accelerate patch deployment.

Hardened enterprise edge defences on Cloudflare — WAF rules, rate limiting, access controls, DNS security, and DDoS mitigation.

Ran real-time endpoint monitoring and threat response on Palo Alto Cortex XDR, triaging alerts with Unit 42 threat intelligence to cut MTTD/MTTR.

Reduced critical vulnerabilities through source code review and vulnerability-reduction tooling; reported and helped remediate flaws in Veryon's web assets.

Monitored and triaged alerts on CrowdStrike EDR/SIEM; configured automated incident-response workflows for real-time threat detection.

Deployed Rapid7 InsightVM scan engines for continuous vulnerability assessment of web assets.

Implemented security controls in Prisma Cloud for cloud infrastructure protection and compliance monitoring; improved alert accuracy with IOC enrichment.

Detects and helps remediate poisoned-artifact and dependency risks in CI/CD workflows before they reach deployment.
