About Johannes

I am a Software Architect with over 10 years of experience in designing and implementing scalable cloud and IoT platforms – from architectural decisions to production-ready implementation.
My focus is on modern frontend architectures with Angular and Nx, as well as cloud infrastructures on AWS. I know both sides: as a Technical Lead who designs and implements systems, and as a Professional Scrum Master who empowers interdisciplinary teams to achieve technical excellence.
I am currently responsible for the architecture of a large industrial IoT product at an international mechanical engineering company – including technology selection, system design, code quality, and team enablement.
I can help you with:

Architecture consulting & review (Angular, Nx, AWS)
Technical Lead for existing or new projects
Building and modernizing frontend architectures
Agile transformation & Scrum coaching for development teams

I work remotely, precisely, and on an equal footing – without overhead, directly with you or your team.
