WMF / GroupeSEB

Initially, I took on a Role as a one-stop contact between the customer and the teams provided by external vendors, the internal IT org and the Business Team. The Customer wanted someone with a deep understanding of the technologies involved who was not affiliated with the Vendors to consult the Customer directly.

Later, this became a Leading / Mentor Role in various realms (Project Steering, Agile Methodologies, Software Design). Furthermore, migrating the front-end team from the external vendor to an in-house team in France due to organisational changes became a significant task for the last year. That required Hiring, Ramping, Mentoring, and Managing the brand-new Team.

I was part of the Programm Management Group from the beginning till the end of my mission.

Zusammenfassung

I primarily support customers in implementing software development processes while simultaneously developing products, including tech stack migrations, team building, mentoring, and the development of suitable sustainable architectures, which are the basis of my work. For most clients, architecture, agile process methodologies, and team management are not limited to the front end, as the required trades are often comprehensive. This also includes data protection, data design, and security concepts. My customers and I do not see me as a pure workbench but as someone who helps a customer develop software beyond the time of the commitment that is maintainable and understandable and remains manageable along its life cycle. For me, clean code, testing, process methodologies, code style, and the many other components of the rapidly changing software ecosystem are a means to and not an end in themselves to achieve this goal. I usually get involved in project management & steering questions such as team composition and milestone planning to bring in my long project experience.
