Lufthansa Cargo digital platforms: booking APIs, rules, EDI, and assistance.

Worked end-to-end across CurationEngine, SmartBookingAPI, operational Cargo EDI, and aircraft-maintenance tooling: Spring services, TypeScript UI/tooling, Drools/KIE rule systems, integrations, Kubernetes/CI/CD, monitoring, documentation, and Lufthansa team support. Observability work helped reduce MTTR by 40%.
