Starting with a simple side project turned into scalable products taught the lesson that solving real problems matters more than complex code.
Creating Diolight, an app turning phones into flashlights, led to the creation of more tools and eventually companies like MooxerGames, Dtech A.S., and Wtech GmbH.
Transitioning from a coder to a CEO, the focus shifted to designing scalable systems, managing teams, vision, growth, but still retaining the belief in coding and testing products.
Lessons learned include building real products, valuing feedback over perfection, not waiting for funding, and starting with code before considering the formation of a company.
