Company History

Maerki Informatik was founded in 1986. It is an independent enterprise run by me, Hans Maerki. I am solely responsible for the successful completion of all contracts.
I have been a member of the Swiss Open Systems User Group (formerly Unix Group Switzerland) since 1986. From 2000 to 2008 I was on the Board of /ch/open.
1992 I used Linux (v0.9) for the first time: As a C-Development Environment for a AIX-Project.
I taught at Hochschule Rapperswil for 6 years.
I have worked with Ascom Autelca, Burger und Stocker, Forstingenieure, Lenzburg, Crealogix AG, HP (formerly DEC), diAx Telecommunications, Garaventa Ropeways, HSR, Nexus Telecom, Siemens Security Systems, Six (formerly Telekurs), Tele2 Telecommunication Services AG, Tele2 Telecommunication Services GmbH (Deutschland), UBS Telecom Support Services AG Bartholet Maschinenbau AG (Ropeways)Solcept Neratec (formerly Elektrobit)Ascom (Schweiz) AG Mettler-Toledo (Schweiz) AG Huba Control AG Fela AG
I wrote some user interfaces based on wxWidgets. One of them was the official phone directory of Swisscom Directories AG (Telinfo). WxWidgets is a excellent portable GUI-framework (Win, Unix und Mac). From 2014 till 2017 I worked as Software Engineer at Solcept.
