RomaniaWhat I'm looking for
I am a Senior Cyber Security Engineer with deep expertise in automation, Linux systems, and DevSecOps, focused on securing IT infrastructure and improving system efficiency.
I've centralized logs into SIEMs, built SOCaaS solutions, and deployed security tooling using technologies such as Logstash, Filebeat, Kubernetes, Terraform, and GitLab CI/CD.
I develop automation and integration scripts in Python, Bash, PowerShell (and occasionally Ruby and Perl), and have delivered cloud functions and alerting pipelines that integrate Elasticsearch, Pub/Sub and ArcSight.
I mentor junior engineers, design training paths, conduct technical interviews, and collaborate cross-functionally to research and implement new security technologies.
