Dear employer,
Hi
As you said you are open for suggestions, I have one for you. I can develop a Python code with a simple dashboard (GUI) in which you can load the folder that contains the sales data files and then, click a button. After clicking, it generates an Excel file with your required template and also shows the key performane indicators that you want in a new page (or in the Excel file based on your decision). Also, it can generate the charts that you want in both Excel file and in separate images. I am an expert in Python and this kind of projects. You can read the reviews of other employers on my profile. I can help you with your project. Would you please send me a message so that we can talk about it more accurately?
I am a computer programmer with more than 10 years of working experience using Python, C#, VB.Net, C++, MATLAB, FORTRAN, etc.
I can develop your required code with the highest quality and the lowest price.
Believe me one time and you will start hiring me as a long term employee.
Regards,
Abbas
