Greycastle is currently a single employee consultancy consisting of me, David Dikman.
The company has been around since 2008 but mostly taken on smaller projects whereas I have had full time employment elsewhere.
Since it was founded Greycastle has been involved in the making of:
- A voice IP gateway
- Invoicing software with Visma integration
- A PHP based e-commerce site
- A stowing algorithm & application with 3d interface
Already in 2008 we made our first contact with WPF. At that time we built a Silverlight switch client for a VOIP gateway server. Since then we have written numerous smaller applications in WPF and is currently engaged in the rich desktop client useMango™.
We are born in the era right when the web started. Our first web page was pure html hosted on geocities uploaded with a 36kbps modem. At this point we have written entire web systems in C#, Node.js and PHP.
Although web and desktop are our strong sides we do love new challenges and have as such worked with both Windows Phone and Android creating rich applications for both platforms.
We would love to hear from you, if you got any ideas, questions, suggestions don’t hesitate to drop us a line:
