Freelance Marketplace Platform

A distributed microservices backend for a freelance marketplace: six Spring Boot services behind a Spring Cloud Gateway with JWT-secured APIs, OpenFeign for synchronous reads, and RabbitMQ event-driven sagas that run compensating transactions on payment failure. Uses polyglot persistence (PostgreSQL, MongoDB, Redis, Elasticsearch, Neo4j, Cassandra) with Kubernetes manifests and Prometheus/Loki/Grafana observability.
