DevOps & Site Reliability Engineer focused on automation, scalable infrastructure, and operational excellence.
What I'm looking for
I am a DevOps and Site Reliability Engineer with extensive experience automating deployment processes, provisioning infrastructure, and implementing system monitoring to ensure high availability and performance.
I design and manage scalable, reliable systems, driving CI/CD adoption with GitLab CI/CD, ArgoCD and infrastructure-as-code using Terraform, Ansible, and Helm.
My work has reduced costs, improved query latency by 70% in large ClickHouse estates, enabled zero-downtime migrations to Kubernetes, and improved logging fidelity to 100% with centralized solutions.
I prioritize proactive monitoring, security best practices, disaster recovery, and close collaboration between development and operations to deliver resilient, efficient production systems.
