In this project, I support the software development of various modules of the supply chain management solution. My responsibilities include the technical implementation and optimization of collaborative SCM processes that help companies make their supply chains more efficient, transparent, and resilient. This modular software platform facilitates communication and Collaboration with suppliers is standardized and digitized, enabling seamless traceability of quality data and supplier evaluations. Technically, I focus on development with Go/Golang for scalable backend services and on the use of Kafka for real-time messaging and event processing. I design and extend GraphQL interfaces for efficient data communication between microservices and support automated build and deployment management using Docker and Gitlab CI/CD pipelines. Data is stored in the modules I work on using a PostgreSQL database.
