  • You define technical concepts and identify the suitable tools, methods, and technologies to find solutions for technical challenges. You keep the tech stack up to date and always guarantee your high-quality standards.
  • You still like to write code yourself, but you also like to conceptualise your projects from the beginning and make technological decisions.
  • You are a professional leader in your area of expertise and evaluate the latest technologies, share your knowledge with colleagues, mentor juniors, set priorities, develop goals, and thus actively drive further development.
