Najim J.

As part of the digital transformation of Decathlon's Supply Logistics department, I contributed to the design and development of a new WMS (Warehouse Management System) aimed at replacing the historical AS400 system.

My main achievements and responsibilities include: microservices hosted on GCP. Implementation of an architecture based on facilitating inter-service communication using REST calls and Kafka events. Use of Spring Boot (including advanced versions like Java 19). Adherence to best practices, such as Clean Code, Clean Architecture, and DDD, to ensure the quality, readability, and maintainability of the code. Implementation of exhaustive tests at all levels, from unit to acceptance, to guarantee the reliability of the new system.

Technical environment: DDD, Java 17 / ,Spring Boot 3, Event-driven architecture (Kafka, Debezium, Avro, Change Data Capture, Event Sourcing, Cloud Events), OpenAPI v3, Jooq, Jqwik, JUnit 5, Cucumber, Serenity, JUnit, Kubernetes, GAR, Github Actions, Gravitee, Datadog, AKHQ, SonarQube, Postgres, Git, Gradle, Github, Vault
