Continous development of an Electron-based desktop app

We have an app built on Electron + Puppeteer + React w/ Material UI as a basic interface.

The app interfaces with the web version of a popular online game and automates tasks for the game players.

We're looking for someone familiar with the above technologies to pick up where our previous developer left off (we are currently in a working beta version) and continue to develop the app on a project basis for now.

This can easily turn into a part-time gig for someone that knows how to estimate a time, deliver what is promised for that time and communicates clearly.
