Hi there, My name is Umair. I have good experience with Google Apps Scripts, JavaScript and Google Data Studio. I am a practicing Developer/Designer Since 2015. I can perfectly work on your project which is regarding Google Apps Scripts, JavaScript and Google Data Studio. Based on my experience, I can do this task for you and the quality of work would be up to the mark. However, further discussions are required for more clarity. I will wait for your text to discuss the project in further details.
Thanks & Regards
Umair A.
