What I'm looking for

I’m looking for a DevOps/SRE role where I can own progressive delivery and reliability (zero-downtime, automated rollbacks), optimize cloud costs, and build high-signal observability—so teams ship faster with less operational noise.

I’m a Senior DevOps Engineer focused on making production delivery safer, faster, and cheaper through automation, progressive delivery, and observability. I’ve architected zero-downtime release workflows using ArgoCD and Argo Rollouts while hardening rollouts with smoke tests, metric-based analysis, and automatic rollbacks.

In my current role at Sentilink, I reduced Datadog infrastructure spend by refactoring the agent topology, bringing active instances from 150+ to under 20. I also improved reliability by tracing Linkerd fail-fast behaviors after AWS spot migrations and standardized canary/blue-green pipelines to help development teams ship confidently.

At Tiket.com, I led platform SRE efforts—managing a 7-member Infra Platform and SRE team and building self-service tooling to reduce operational friction. I delivered infrastructure cost savings of ~4,000 USD per month by optimizing CI/CD pipelines and data retention/storage footprints.

Earlier, I strengthened Kubernetes observability and operations across multi-cluster environments by converting JSONNET definitions into Helm charts, building a custom Fluentbit/Fluentd Ruby logging plugin with rate-based throttling, and creating telemetry dashboards with Prometheus, Grafana, and Python metrics. I bring that same systems mindset to infrastructure-as-code with Terraform, Ansible, and CloudFormation, backed by AWS and GCP cloud engineering experience.
