At CareEvolution, I engineered a .NET 10 and YARP replacement for the API gateway as the sole developer. It sustains 100 RPS with payloads up to 150MB and has had zero gateway-related downtime in three years of production.

I own the AWS platform behind Orchestrate, CareEvolution’s cloud-native healthcare data-integration product, used across 200M+ lives. I also own its customer-facing React/TypeScript portal, serverless services, CI/CD, and platform observability, including work on systems handling billions of records.
