Hi there and welcome on steffr.ch! My name is Stefan Rüetschli and I’m interested in computer-networks, programming and information technologies. I finished my apprenticeship as electrician in 2003, then I worked 5 years for an internet service provider. During this time, I completed further education in telematics (Java, PHP, communication technologies, projects…). From 2009 until 2017 I was working for a security company where I was responsible for security management systems. In 2009, I received the FCNSA and FCNSP certification, in 2013 I received my certificate as CCNA. In 2015 I got the chance to expand my knowledge of VMware with a VICM (VMware Install, Configure, Manage) training.
Since 2017 I’m working again for an internet service provider which is quite interesting. I’m working with network equipment from core to end-user, firewalls, virtualization and the VoIP platform.
If I have some spare time, I work on some of my iOS Apps and try to understand objective c 😉 A first result of this was the Cheat-Database App. Because of lack of time I had to cancel my Apple developer account, thus the App disappeared from the Store ;(
Of course, I maintain this blog and update it with themes I’m currently interested in like Photography, Linux, Raspberry Pi, Arduino, Multicopters, Penetration Testing etc…
