Hello there!
I'm Chris, a dedicated C++ software developer that specialists in desktop applications. I primarily work with the wxWidgets framework and Unity3D to create software that works across multiple systems and platforms.
Your idea interests me a lot, as both a developer and an avid Hearthstone player. I've spent many years playing card games, some online, and know exactly what it is you'er looking for. In fact, I've done similar myself as part of a couple of other projects whereby users would log on to manager collections of game items.
I have placed my bid according to your description for a collection manager, though I would be both excited and able to pursue the project at large with you if so desired. I believe you'll find my feedback on here perfect for the work I've done so far, and I will be glad to give you further references, code samples or instances of work I've done elsewhere in order to demonstrate my ability.
I'm extremely excited by this project and am very keen to get started working together.
Have a great day!
Chris
