Hello,
I am experienced nodejs developer and i can make your electron task time.
As stated, tasks that are finished will be saved on database, and administrator will have a report on every task for every user.
I did not use electron, but it is web app based on desktop browser, so rules are similar like programming a regular website.
Service will go under QA on every aspect, and myself will offer a one year service on service that i will build.
Contact me if you are interested
