What I'm looking for

I seek a role focused on SRE or cloud infrastructure where I can improve uptime, automate operations, and drive cost-efficient, secure, scalable systems within a collaborative, forward-thinking team.

I am a Senior Site Reliability Engineer with extensive experience maintaining and optimizing complex, cost-efficient cloud infrastructure. I specialize in Kubernetes, Terraform, Linux and cloud-native technologies, and have led large-scale cluster operations, multi-region setups, disaster recovery, and identity migrations for hundreds of users.

I deliver automation, observability and secure operations—improving alerting in Prometheus, enabling external monitoring, tuning Envoy, defining WAF rules, and automating CI/CD pipelines. I thrive on driving uptime, operational excellence and infrastructure efficiency for forward-thinking companies.
