- agentic-mcp-gateway — MCP server + agentic RAG tools (retrieve docs, search payments, create tickets). Runs without an API key.
- banking-payments-spring — Spring Boot 3 / Java 17 payments API with JWT, idempotency, Kafka events, ISO 20022-inspired flows. My own demo, not bank IP.
- kafka-spring-microservices — Transfer API, double-entry ledger, and notifications over Kafka, with docker-compose and Kubernetes manifests.
