Simon helps software companies design scalable software systems by supporting them with solving architectural challenges, mentoring, and coaching developers as well as decision-makers with his company Lasssim. He started his professional life in chip design, but he’s always loved software more. Not just because software is way more agile than hardware development, but because tackling bigger problems at higher levels of abstraction is more appealing to him. This also explains his love for Software Architecture and Microservices in particular. In his years working at Runtastic Simon helped to scale their backend, infrastructure, and mobile apps from a couple of users to more than 130 million registered users and 245 million app downloads.
