What I'm looking for

I’m looking for a role where I can own production AWS + Kubernetes reliability, build automation to reduce operational errors, and improve observability and cost allocation—working with teams that value least-privilege security and measurable reliability.

I’m a Site Reliability Engineer focused on production AWS infrastructure, including Kubernetes clusters with ~30 nodes. I manage EC2, S3, Aurora, VPC, CloudWatch, Lambda, Route53, Cognito, Transfer Family, and Secrets Manager while upgrading, troubleshooting, and scaling nodes to keep services stable.

I build automation with Python, Bash, and n8n to reduce operational automation errors and save over 6 hours per week. I also strengthen reliability through IAM least-privilege design, and I lead observability and cost ownership work—like AWS tagging restructuring covering 85%+ of monthly spend—so teams can operate with clearer visibility and safer access.
