At Vonage By Ericsson, I led and mentored a six-engineer SRE/DevOps team building a self-service Kubernetes developer platform. We cut onboarding time to one day and increased deployment frequency by 200% within 12 months.

I overhauled incident management and on-call practices, bringing median P1 incident MTTR below 60 minutes and reducing repeat critical incidents by 35%. I also directed GitOps-based cluster provisioning that brought EKS setup to 90 minutes.

At Vonage By Ericsson, I drove platform cost and scaling improvements, including a 30% improvement in per-core cost efficiency and faster pod scheduling through Karpenter and KEDA. I established progressive delivery practices that reduced CI/CD cycle times by 80%.

At MO ENGAGE, I led reliability and cost initiatives for a multi-region engagement platform, including immutable AMI pipelines and blue/green releases that reduced deployment time to 2–3 minutes. More recently, as a self-employed consultant, I architected and deployed a hybrid Gen-AI gateway on EKS, integrating self-hosted inference clusters with a serverless cloud provider.
