Hi,
I am an experienced freelancer, developing in Web Domain for the last 7 years and in NodeJS domain for the last 2.5 years along with ExpressJS, SocketIO, WebRTC, etc
I do not have any completed ElectronJS products as such but I can assure you that I can complete your project.
If you still want some samples then you can ping me and I can make one for you.
And as far as the requirements goes, I have already implemented a local database in SQLite for an Online Automated Code Compilation System I created using NodeJS, ExpressJS, SocketIO.
Looking forward to work with you.
Thanks.
