Multi-region platform and one-click deploys for a healthcare SaaS

Redesigned the infrastructure of a healthcare SaaS for the US market and cut cloud cost by more than 60%.

Situation

As CIO of a healthcare SaaS for the US market, I owned an infrastructure that ran a large number of customer services. Deployment had to be repeatable, the setup had to account for HIPAA and GDPR, and cloud cost per service was too high.

What I did

Built a deployment API in Express and TypeScript that creates a service, its domain and SSL in one step
Moved services to Kubernetes on Azure (AKS) and standardized deploys with Helm charts and ArgoCD
Designed multi-region infrastructure with HIPAA and GDPR requirements in mind
Managed the infrastructure as code with Terraform, CI/CD on GitHub Actions
Set up monitoring with Grafana and Prometheus

Result

More than 500 global services ran the same way, and cloud cost dropped by more than 60%, from about $15 to $5 per service.
