## About

```text
At Egencia — American Express Global Business Travel, I own the delivery path for 8 platform services, replacing manual per-environment deploys with a GitHub Actions, ECR, ArgoCD, and EKS flow that ships production releases daily. I also replaced hardcoded AWS credentials in CI/CD with Terraform-managed OIDC roles.

I built self-service Kubernetes routing and unified platform checks in Prometheus, Grafana, and Alertmanager. As part of the platform team, I migrated 4 ML model-serving workloads from AWS SageMaker to Amazon EKS, cutting monthly compute cost for the highest-traffic inference workload 66%; at FanDuel, I helped scale Kubernetes workloads for NFL season peaks and built self-service provisioning for live sports video channels.
