Beratung und Programmierung von Teillösungen und schlüsselfertigen
Komplettsystemen. Beratung, kleine Projekte etc. sind oft kurzfristig möglich.

Zwei Schwerpunkte:

1.) UE/GUI Design. Erfahrungen bei Projekten mit Nokia, Vodafone Global,
Sony NetServices, HBM, Allianz, BMW und Ericsson Prototype Unit. Konzept ganzer Applikations-Suiten oder Verbesserung einzelner Flows.

2.) Konzentration auf moderne Technologien wie browser basierte Anwendungen, AngularJS (SPA - single page applications), Meteor, node.js sowie native Android.


Ältere Skills:

.net Compact Framework für "managed applications" und PocketPC, Smartphone
embedded Visual VB und C++ für native Programmierung der mobilen
Microsoft-Platformen.

BlackBerry Java API

Durch meine Erfahrungen im Verlagswesen und bei der Software-Entwicklung kann
ich meinen Kunden insbesondere im Bereich Publishing (auch eCommerce, WAP etc.)
Hilfestellung von der Beratung bis zur Abgabe schlüsselfertiger Projekte
geben.

Hierzu steht bei Bedarf ein eingespieltes Programmiererteam zur Verfügung.

Seit 2001: Erweiterung der Geschäftstätigkeit in Richtung mobiler Endgeräte
wie Handies und PDAs. Seit 2003 bin ich für die Java und die Tools-Section
der internationalen Entwicklersite "Forum Nokia" verantwortlich.
