    • Internet and Information Technology
  • CTO (Interim, As-a-Service)
  • In the position of an interim CTO, I was building a team for the further development of an MVP for the automation of class action suits - especially for cases related to the Volkswagen exhaust scandal, as well as building up a suitable platform for the development of software (in highly-distributed teams).

    My main activities were the analysis of an already externally developed MVP (minimum viable product) with the focus on the further development of new features by a dedicated core team. I have chosen appropriate programming languages, technologies, and architecture. I took active participation in the hiring process of suitable developers, established a development process, lead the team, wrote code, and solved various DevOps tasks.

    • Roche Diagnostics IT Solutions GmbH
    • 250-500 employees
    • Pharmaceuticals and medical technology
  • Senior Software Engineer
  • In Roche, I have been a member of an agile team that developed software that is part of Roche´s SWISSLAB laboratory information system. I was involved with the entire development process, which included requirement analysis, architecture, specification, and implementation.

    I introduced the Mikado method, which is a tool to analyze, break-up, visualize, and structure refactorings that are too complex to get solved in a single iteration. This method helps to make complex development tasks estimable and to scale them so that they can be distributed optimally to available developers. This particular agile method allowed the team to solve technical debts in legacy code much more straightforward.
