What I'm looking for

I’m looking for a role where I monitor SIEM alerts, investigate incidents with clear RCA, harden access control/MFA, and support multi-cloud (AWS/Azure/GCP) operations—backed by strong documentation and cross-team collaboration.

I’m an IT Professional with hands-on experience in security monitoring, log & alert analysis, incident handling, and access control across on-premise and multi-cloud environments (AWS, Azure, Google Cloud Platform). I’m comfortable analyzing system logs, supporting audit & compliance documentation, and communicating findings clearly to management.

In my work, I’ve coordinated with cross-functional teams and vendor/SOC teams to resolve issues and improve system security. I focus on vulnerability & asset audits, root cause analysis, and consistent operational documentation—especially when working under pressure in fast-paced, cross-functional settings.

I’ve supported multi-cloud reliability and performance through monitoring and incident response, while also strengthening hybrid architectures through secure connectivity and deployment documentation. I’ve contributed to automation scripts and CI/CD-aligned workflows to improve stability, availability, and reduce manual effort.

I also bring a strong infrastructure and networking foundation from hands-on system administration and troubleshooting—covering Windows/Linux environments, Active Directory, firewall rule enforcement, and network security fundamentals (Cisco, Mikrotik). My CCNA, MTCNA, and cloud security certifications (including Amazon Web Services Cloud Practitioner, Microsoft Azure 900, and Alibaba Cloud Security Associate) keep me focused on continuous improvement and measurable security outcomes.
