Projects
Ordered
My marketplace backend, built as Spring Boot microservices (user, product, order and engagement services) behind an API gateway, with Eureka service discovery and a Config Server. I decomposed it from a monolith with the Strangler Fig pattern, using Kafka with a transactional outbox, JWT authentication and Resilience4j circuit breakers, and monitored with Prometheus, Grafana and Jaeger. Running in production, with an interactive API explorer on this page.
