Hi,
I am not from Pakistan but I have 3 years working experience with Embedded System and all these microcontrollers that you mentioned above. Besides, I also have experience with wxPython and Tkinter, which used to build GUI.
Although I am newbie to this website, I have been working with many customers like you on other platforms, so do not worry.
I hope that we have a chance to work together, just inbox me to have a free consult.
Thank and looking forward to hearing from you soon so we can get started asap.
