Richard Sedellke, pixelquadrat
A performant, scalable, and consistent data infrastructure is a key part of business success. pixelquadrat develops databases, data models, and reports based on MS-SQL and builds interfaces to transfer relevant data records from third-party systems into your own software.
Based on C# and dotNet, pixelquadrat
develops complex software, software applications, and cloud-based software solutions to your specification.
We're also happy to help with developing your mobile software application for Android and iOS.
Using the latest web technologies such as html5, css3, jQuery, and JavaScript, pixelquadrat creates web applications, shop systems, and complex software intranet solutions that display equally well on any device (smartphone, tablet, or PC).
With the "Single Page" concept, all the important information is arranged one below the other in a clear layout. Present your products, your company, or your services in an appealing, modern way and turn visitors into customers.
Your website is displayed equally well on any device, whether laptop, tablet, or mobile phone, and automatically adapts to the screen resolution.
The rapid development of mobile devices and tablets has revolutionised user navigation, so that people now "swipe" and "flip" through the individual pieces of information on a website.
While viewing the website, texts and images are automatically loaded in the background, so there are no waiting times.
