AlterX – ITSM Change & Incident Management Platform

AlterX is an internal ITSM platform designed to manage technical changes, deployments, incidents, and post-incident analysis within enterprise IT environments.

I developed 3 core microservices: User Management, Organization Management, and Incident Management, following Hexagonal Architecture, Domain-Driven Design (DDD), and CQRS principles.

The platform includes:

* Microservices-based backend architecture with Spring Boot

* Secure authentication and authorization using Keycloak, OAuth2/OIDC, RBAC, and JWT

* Event-driven communication with Apache Kafka using the Transactional Outbox Pattern

* Resilient service-to-service communication using OpenFeign and Resilience4j

* Angular administration and incident management interfaces

* PostgreSQL database

* Docker-based development and testing environment

* Automated testing with JUnit 5 and Testcontainers

The project was designed to provide a structured alternative to manual change-management processes while improving traceability, security, and coordination between technical teams.
