Developer / IT ProfessionalApart from learning about digital technology and computer science in my training as an electrical engineer, I have no official training or school qualification as a developer. In the 20 years I have read quite a few books and intensively studied their domain for each customer or employer. This ranged from physics calculations for heat consumption to e-commerce processes to printer cartridges. In my work in teams of various sizes, I have found few gaps that would have justified a computer science degree. Domain Driven Design, SOLID, Kanban, Scrum, BPMN are natural for my daily work.
