Tätigkeitsbeschreibung

J. joined different teams at the same client:

J.'s team was tasked with many cross-cutting concerns, meaning working with both backend and frontend tasks. The backend was thereby responsible for the mobile apps, a web application for the customer and a web application used in the store. This required quickly picking up new techniques and understanding different parts of the system and how they work together.

J.'s team was in charge of developing features to provide sample orders including customer notifications, setting up a training environment for the employees in the stores, deploying features to provide deployment without downtime, creating a mechanism to reply business events to provide reports and implementing different features multilingual. In addition, he worked with several partner integrations such as fulfilment, payment, several SAP systems and point-of-sales terminal. Furthermore, J. setup different Kibana dashboards for monitoring and visualizations of log data.

New teams were formed at the customer with the responsibility of providing the customers information about their ongoing or past orders by creating an appropriate micro service landscape.

The micro service consumes and communicates via events over Apache Kafka and gets deployed on a Kubernetes cluster. By choosing these cutting-edge technologies the team is creating a service that can be independently scaled with ease.
