I worked on a migration project from Commerzbank to Societe General where good communication was an essential part of day-to-day work. There was a lot of stakeholders on both sides with different opinions and goals. To add to the complexity, we worked as a distributed team with developers in Prague, Budapest and Frankfurt. I was communicating architectural decisions both across our development team as well to the business to maintain clarity on where we are headed and which targets we had. I was responsible for integrations in the new organization, as not all systems were transferred.

With Lufthansa I worked with Enterprise Architecture where we defined the strategy for the whole Lufthansa Group. There I specifically was the cloud and integration architect, setting guidelines and best practises for 20-30 architects in the different business units. Lufthansa has a multi-vendor strategy also when it comes to cloud, so I got to dive into both IBM Cloud and Microsoft Azure. On the integration side I focused on selection of an API Gateway product that itself had to integrate with the existing security-, identity- and authentication infrastructure. For showing the solution architects and developers in the individual business units the validity and value of the architectural decisions my team made, I implemented a few Proof-Of Concept projects. The source code for these were distributed to the internal developer network and contained demonstrations of the use of

• Kafka for streaming/queuing
• Grafana for visualization
• Telegraf for monitoring
• Enterprise Architecture
• Cloud Architecture
• Service Integration

At Thomas Cook I was leading an integration team in the context of operational data, ranging from live tracking and messaging data directly from the aircraft, over communication with the airports, to customer facing data. There were several functional overlaps in the systems as just before my entry, four airlines had to merge, both from a business process view and a system perspective. As we had little control over the source and target systems, we build integrations towards many kinds of technologies, RESTful, SOAP, API Gateways, (S)FTP to name a few. To integrate all data and to make sure it was distributed correctly we had an ESB product, but due to the complexity of maintaining a record of which data was considered the master data, we ended up heavily extending the off-the-shelf product, using a microservice architecture. To facilitate the developers, I setup a cloud-based CI/CD based on Azure DevOps. In this role I reported directly to the CTO of Thomas Cook Airlines Group.
