**3. Details on tech stack**
C# front end development. Since the app has rich interactive trading screens, they do not use browser based apps, rather thick clients that use WinForms, with a desired migration to WPF. So having WPF/.NET skills for the C# developers will be key. This is sort of like having those rich Bloomberg trading screens that you might have seen, lots of stuff on the screen, green and red colors, etc. An example the app typically pump up to 8000 messages/sec to the trading screens, and the screens are constantly getting refreshed. The front end client is installed on every trader’s desktop. These workstations are CPU intensive, and also have very high end graphics card – these are all typical in a Wall Street trading shop.
