Document end-to-end data flows, including persistence, messaging, and integration touchpoints.
Interface and Integration Analysis:
Analyze HL7 and RPC interfaces to document message structures, behaviors, and dependencies.
Identify integration patterns and constraints impacting modernization sequencing.
Modernization Architecture Guidance:
Translate legacy analysis into target-state architectural guidance for modernization teams.
Define service boundaries, integration strategies, and migration approaches aligned with modernization goals.
Modern Platform and Cloud Architecture Awareness:
Provide architectural guidance across modern platforms leveraging Amazon EKS, Docker, and Kubernetes.
Guide use of modern backend stacks including Java 17+, Spring Boot, and Spring WebFlux.
Data, Messaging, and Caching Architecture:
Provide architectural input for data platforms including Oracle DB and Amazon Oracle RDS.
Guide event-driven architectures using Kafka.
Advise on caching strategies using Redis and Amazon ElastiCache for Redis.
Networking, Observability, and Resilience Context:
Consider networking and traffic patterns involving Amazon Route 53, AWS NLB, and AWS ALB in architectural planning.
Incorporate observability considerations using Grafana.
Account for service-to-service communication and resilience patterns using Consul Mesh.
Cross-Team Coordination and Technical Leadership:
Serve as a technical authority across modernization teams, resolving architectural questions and dependencies.
Coordinate closely with architects, engineers, analysts, and stakeholders across M1-M4 teams.
Documentation and Knowledge Transfer:
