About Me
Hi β I’m Jonas Quintiens
I combine hands-on systems administration experience with practical software development to help small businesses and teams build reliable, secure, and maintainable systems. I work as a systems administrator at the Medical Center for General Practitioners and run my own software development consultancy focused on web development, security consulting, and system architecture.
