At AVANTEL LIMITED, I supported Linux-based systems and RTIS infrastructure in production, troubleshooting system, network, and service issues. I monitored deployed devices and contributed to incident investigation, remediation, and production validation.
In authorized web application and network security testing labs, I assessed vulnerabilities using manual techniques and tools including Burp Suite, Nmap, and Nessus. I validated findings, prepared PoC evidence, and documented remediation recommendations; I also built an Active Directory security-testing lab.
