About Me
I am a Senior Enterprise Architect at Deutsche Lufthansa AG within the Service Factory 'Flight Operations & Crew'. With more than 10 years of consulting experience in various IT roles, I am responsible for shaping the target architecture and ensuring architectural compliance of over 100 IT systems. My job ranges from day-to-day (change) request management, where the ideal solution architecture needs to be identified, to the long term goals and vision of the business processes and IT structures within the domains. The key drivers are
- need for increased satisfaction of the business teams and reduced time to market for innovation and day-to-day requirements
- leveraging synergies between the group airlines
- increasing architectural alignment and governance in the IT systems and processes towards a more efficient and effective organization
- cost reduction, minimization of IT redundancies, and harmonization with the group airlines increasing overall efficiency
- proactively providing technical innovation and digitization solutions to the business departments to enable new concepts and business models
In the past I have worked in various different roles such as architect (functional and technical), business analyst, developer, tester and team lead, and have repeatedly proven myself as trusted advisor. I like challenging projects and understanding previously unknown technologies and business problems. I have experience with global delivery in multi-national teams and worked on task forces to resolve complex issues. My methodogical expertise ranges from structured waterfall, Rational Unified Process, to agile/SCRUM approaches. I have learned to acquire, refine and shape the big picture: what is the business problem and which technologies can help to solve it.
Experience
I have experience from a variety of commercial and private projects in different roles, across different industries, and a number of different project environments.
2020 - 2021
Eurowings Discover is a wholly-owned subsidiary of Deutsche Lufthansa, based in Frankfurt. It is a leisure carrier that targets holiday destinations in the Caribbean, South Africa, North America, and the Indian Ocean. The airline was built from the ground up. As an Enterprise Architect, I shaped the Crew Management landscape for Eurowings Discover and worked in many different areas ranging from technical setup in the cloud to integration between applications and data mastership considerations.
2018 - present
The Crew Planning domain comprises a large number of different applications ranging from small tools to complex planning applications, optimizers, and rule engines. The entire landscape has grown for over 30 years as the crew planning processes became more and more electronic. Several tools are approaching their end of life and new challenges arising from the digitization of an entire industry need to be addressed: mobile devices, highly variable loads, open/standardized system integration, and analytics. At the same time, a new generation of planning systems is entering the market, significantly changing the way business is done, shifting to sophisticated long-term capacity planning with feedback loops, management by exception, smart problem solvers, and first ideas on machine learning and prediction. The challenge for the Domain Architect is defining a way forward: what should the CMS landscape look like in 5-10 years, what are architectural goals, and how can a seamless, low-risk migration scenario from the existing applications to a new generation of tools be implemented?

Smarter Modeling of IBM Master Data Management Solutions
Co-author of Redbook SG247956. This publication presents a development approach for master data management projects and for projects based on InfoSphere MDM Server in particular. It focuses on the characteristics of transaction hub implementations and the associated business modeling challenges. It discusses the appropriate methods and tooling that can support design andimplementation requirements for master data management in a transaction hub implementation. This book also discusses the principles of domain-driven design (DDD) and, more generally speaking, model-driven development (MDD). It also describes preferred practices for large and small projects. It is meant as a guide for any type of data-centric solution that needs to be embedded into a service-oriented architecture (SOA) and is not limited to master data management solutions. This book focuses on the design phase of master data management projects. Although it discusses other phases, it does not provide details of the implementation and code generation phases.

Workflow Management Concepts for Agile Long-Term Workflows
Over the course of the past 15 years the business environment has significantly changed. Enterprises are no longer limited to local markets. In order to work effectively, they have to be agile and constantly adapt their business processes. Traditional Workflow Management software solutions are limited in their support for this kind of environment, often working under the precondition of standardized, repeatable processes. Current research is focused on a new generation of Workflow Management Systems that allows modifications to individual workflows even while they are undergoing execution. Contrary to traditional approaches such applications must provide concepts for suspension, locking and recovery that are minimally invasive but yet able to ensure consistency of modifications. This book provides a detailed overview of the motivation for this kind of system as well as an architectual concept for the implementation that covers the most frequently used workflow patterns.

Java-basiertes automatisiertes Test-Framework
Co-author of journal article. With an increasing number of software-systems built using components, software developers are faced with entirely new challenges. For example, testing these mod-ular systems has become far more complex. Manual test approaches are incapable of dealing with the new architectures, leaving several parts of the systems untested. Thorough tests require extensive use of human resources, with enormous financial repercussions. Most customers are unwilling to accept these, completely unaware of their eventual benefit. Even existing automated software test approaches can only remedy these problems in parts. They commonly require source code access to add the necessary test routines, making the approach unsuitable for third party compo-nents. The innovative CBTesten approach tackles this problem. A highly dynamic framework is introduced into the software-system after compilation, which allows deriving of test cases as well as fully automated tests based on the collected data.
2004 - 2006

Design software systems and their architecture according to agile principles
Software architecture is increasingly being developed by self-organized teams with shared responsibilities and in an iterative fashion. New skills are needed by developers and architects alike – they include technical expertise as well as methodological and communicative aspects. In this seminar you will experience how agile principles change the way we work on software architectures and how architectural practices are embedded into agile processes and methods like Scrum. New techniques, interesting ideas and good practices are introduced in small batches as we iteratively make our way through a sample project. You’ll have a hands-on experience of a new architectural discipline. A discipline that doesn’t focus on a sole mastermind architect, a disciple that is based on agile and lean concepts and is a natural fit for agile contexts. A discipline that emphasizes pragmatism and transparency.
