I have been working in Linux system administration and backend software development for over 25 years. The first 8 years as an employee, later as a freelancer. Over the years, I have specialized in the development of efficient solutions for scalable, fault-tolerant applications. My focus is on the development of microservices, APIs and distributed services. During my professional career, I have gained extensive experience in the development of software solutions and the operation of Linux servers in large data centers. In addition, I am always eager to expand my knowledge and skills but also to pass them on to customers/colleagues.
