What I'm looking for

I am seeking a role where I can lead automation and infrastructure projects, improve system reliability, and collaborate across teams to scale resilient production systems.

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.
