14 Go Microservices
Claims, eligibility, enrollment, billing, provider, notifications, triage, care, consent, and more - each with its own schema and event streams.
Insurance Domain
Policies, coverage terms, claims adjudication, prior authorizations, billing cycles, provider credentialing - all modelled and explained.
Event-Driven
Kafka event catalog covering all domains. Outbox pattern for guaranteed delivery. Temporal workflows for long-running sagas.
UK-GDPR by design
Keycloak identity with tenancy enforced in application code; TLS in transit; consent capture, audit trail and GDPR Article-17 erasure implemented in the consent service. Field-level encryption, OPA/ABAC and RLS are designed, not yet built - see Data Protection.
AI Triage
LLM-powered medical triage engine with decision tree traversal, differential diagnosis, and care pathway recommendations.
Ontology & Catalog
A 117-term ontology aligned to FIBO, FHIR, SNOMED-CT and Socotra, published in OpenMetadata with the ~80 Olly domain tables linked to the concepts they implement.
Self-Hosted
A self-hosted open-source data plane (Kafka, OpenSearch, Keycloak, Temporal, Novu). Today it runs on two docker-compose dev VMs; Google Kubernetes Engine is the production target, not the current deployment.
