Lakshan Sameera
Security Engineer | SOC Operations
Hi! I'm Lakshan Sameera, but you can call me Sameer. As a revert, this name holds special meaning for me.
I'm a Cybersecurity Graduate (NSBM/UoP, 2025) with First Class Honours and an experienced Cybersecurity Professional with 1.5+ years of hands-on expertise in offensive security, SOC operations, threat detection, and SIEM engineering across platforms like Azure Sentinel, FortiSIEM, Splunk, and IBM QRadar.
I've designed and implemented advanced detection rules, automated SOC workflows, and investigated real-world cyber attacks using cutting-edge tools and cloud-native services. My work includes penetration testing, malware traffic analysis, threat hunting, and the development of hybrid SIEM architectures with incident response playbooks to strengthen organizational security.
With strong experience in AWS cloud security, I've engineered threat detection pipelines using Wazuh, AWS Lambda, and Amazon GuardDuty, and integrated Amazon Bedrock for AI-powered alert analysis. These systems support fast, scalable, and intelligent security operations in modern cloud environments.
Driven by precision and speed, and proudly ranked in the Top 2% globally on TryHackMe, I constantly refine my skill set to stay ahead of evolving threats and contribute meaningfully to high-performing security teams.
