Highlight — 2006 to today

dreizehnelf

In February 2006 I founded dreizehnelf as a one-person web consultancy. For its 20th anniversary I'm shifting its main focus from web to media and AI, and building out the studios and publishing that sit around it.

Some highlights of twenty years of web projects

Independent work: microsites localized for 12 countries, Bluetooth hardware apps and firmware, and complete web-to-mobile stacks.

01 2010 — 2015

Sto

For the agency FKD Visuals I built a series of campaign microsites for Sto, the maker of insulation systems, paints and facades: front-end development, localization into up to ten languages and variants, and responsive layouts. I also created the complete i18n/l10n infrastructure used to facilitate the translation workflow with external partners.

Habitron

For Habitron, a maker of home automation systems, I worked across the stack: Linux server administration, software development in Python and microcontroller firmware development in C/C++. Also a hybrid web app in HTML5 and JavaScript, which controls lights and blinds, monitors windows and doors and regulates heating over home Wi-Fi or the internet. I also designed and maintained their whole software development process including version control, documentation, analytics, CI-pipeline and release management of the SmartServer and SmartWeb products.

03 Prototype

Herth+Buss

For Herth+Buss, a family-run supplier of vehicle parts and electrics, le electronic and I were tasked to create a prototype to replace a hardware control surface they used to connect to one of their trailer testers. The idea was to use a smartphone with Bluetooth Low Energy connectivity and a custom app instead. I built a python communication/simulation tool to properly test and verify the communication side as well as a matching mobile app for iOS and Android via Cordova.

Alongside and in between

A constant, with chapters around it

01 Alongside
