Hi there!
We're a team of professional programmers who code in C#, java, python, and many databases (mysql, mssql, db2,..). We're here to bid on your project, because we believe we can do this software highly adjustable and nice working. Our idea is to make a software that will run in background and in case numlock is enabled (or what you prefer) and some of those numbers is pressed X action will be performed. These actions could then also be defined in a gui which will be integrated into the app. We can do this in C#, and this app would work on windows environments. Also as a professionals our code is tested with unittests, we offer future adjustments or anything you need and as you may see all our customers are very satisfied with us - because customer is the king for us! Let us know what you think and then we can proceed with way of work. Also we are very negotiable about everything.
Best regards,
gogamers team
