Spearheaded the zero-downtime decoupling of core monolithic justice administration systems into secure, containerized Spring Boot microservices for the Federal Office of Justice (*Bundesamt für Justiz*).
• Architectural Implementation:
- Modernized mission-critical legacy Java EE administrative workflows into decoupled microservices adhering to strict BSI IT-Grundschutz security compliance.
- Standardized REST / OpenAPI gateways with Keycloak SAML/OIDC federated identity management for secure multi-agency interoperability.
- Supported peak public and inter-agency access spikes with sub-100ms response latencies and high availability.
- Built automated end-to-end security regression test suites and container hardening preventing data leakage across distributed ingress gateways.
