HealthcareMENADevelopment
Modernizing a healthcare ISV from a .NET monolith to cloud-native services
Decomposed a 12-year-old .NET monolith into bounded services on AKS with strict HIPAA-equivalent controls, in 9 months and without a freeze.
Client: A regional healthcare ISV
Challenge
What we walked into
The monolith blocked multi-tenant rollouts. Releases required full regression cycles. Customer outages on shared infra were trending up.
Approach
How we engaged
- ●Strangler-pattern decomposition — extracted high-churn capabilities first
- ●AKS with private networking, customer-managed keys, and audit-ready logging
- ●Test pyramid rebuilt with Playwright + contract tests + load tests on k6
- ●Zero-downtime data migrations with dual-write and shadow-read patterns
