- Ran 20+ web app and API penetration tests across the production platform, manually mapping the attack surface to uncover IDOR, stored XSS, and authentication bypasses missed by automated scanners; drove a 40% reduction in critical vulnerabilities.
- Secured VPS infrastructure from the ground up: rewrote firewall rules in the IONOS Cloud Panel, configured a NAT Gateway for outbound-only VM exposure, enforced SSH key authentication, and established a patching cadence that maintained 100% production uptime.
- Deployed Cloudflare WAF in front of production with custom firewall rules targeting active scraping and DDoS patterns; configured rate limiting and Cloudflare Access to put internal tooling behind strict identity verification.
- Neutralized a live cryptojacking and data-exfiltration attempt by tracing process trees, cron persistence, and outbound C2 traffic; evicted the loader, remediated the initial access vector, and authored custom Splunk detections to prevent recurrence.
- Directed quarterly attack surface reviews with the CTO, translating technical findings into business risk and co-designing network segmentation that reduced overall exposure by 30%; authored the company's foundational incident response playbook.
