Chief Technology Officer (CTO)
Information technology is my life and I have a solid education as an information technician. I have started with digital signal processing and network technologies, Learned binary operations and programming at a very low hardware level. Over the years, I've been working on countless projects, creating and working with different websites. In doing so, I have always been up-to-date with the technological development And I've worked with modern techniques and frameworks to make them useful. Programming has changed over the years and has become easier and faster. Today we have modern languages and SDKs available. Management techniques like Scrum and helpful tools like Trello support us, to manage projects and to keep track of subtasks, the code versioning (Git) ensures the smooth working together in groups. You have to ask yourself some basic questions, before you start programming the first code line. You have to think about deployment, backup, scalability, database model, programming language, framework and many other topics. Sound knowledge is helpful in selecting the right technology for a task, But experience can not be replaced by anything. That's why you never stop trying out new things and learning more about them.
