At Riipen, I conducted penetration testing on web applications and identified and resolved critical security flaws, including SQL injection, XSS, and API vulnerabilities. I used Burp Suite, OWASP ZAP, and Nmap to analyze threats and improve system defenses.
I also developed detailed risk reports outlining vulnerabilities and solutions. This work contributed to an improved security posture.
For my Windows Server Infrastructure Deployment project, I deployed a server environment with Active Directory, DNS/DHCP, Group Policy, and internal file sharing. I also configured IIS hosting and carried out disaster recovery procedures.
