Freelancer profile translated to English.

Description

I am a passionate Solution and Software Architect with years of experience in both developing and designing software architectures, as well as leading and managing development teams.

I manage software development and lead development teams both in the company I co-founded in 2019 and for client projects.

Before that, during my PhD in Astroparticle Physics, I gained experience in handling large amounts of data with limited computing resources (primarily using Python and C++).

Due to my many years of experience, I am familiar not only with development but also, in particular, with the planning and design of IT and software architectures. I enjoy working on architectural designs just as much as I enjoy managing their implementation in development teams.

I do not see software development as an end in itself, but in the context of challenging and interesting client projects, in order to deliver meaningful added value. I am happy to accompany and support companies in their digital transformation!
