A few words
about me.
15+ years in software, currently a Tech Lead in eMobility. I lead the development of CPO and eMSP platforms with over 10,000 EVSEs. I always start by understanding the business: who uses the product, how it makes money and what really matters to the client. Only then do I choose the technology. In my free time I build things I'm passionate about.
