MDS - Medication Data Service

A cloud-native, HA microservice application for medication metadata handling and medical screening. The intended use case is to provide centralized medication information and interaction/screening, which also check services for every PK CPOE client. I designed and delivered a completely automated GitOps pipeline utilizing GitHub actions and Argo CD rollouts into production. The pipeline included automation for both code delivery and scheduled data updates. Every deployment proceeded through the canary scenario, and analysis was conducted with Kubernetes job integration tests.

ERX - Electronic Prescription Processing

A cloud-native HA application for electronic prescription processing. The intended use case is to handle discharge prescription orders for 400+ hospitals nationwide. The list of microservice subdomains included: prescriptions, providers, pharmacies, formularies, prescription benefits, and medicine/medical history.

GraphQL API Federation

I created several tools that can be used to quickly and efficiently convert existing REST API endpoints to GraphQL.

I developed custom scripts to handle the conversion of complex data structures and query operations and deployed them on the federated Apollo server.
