This looks awesome, that video is slick! I looked into getting into open source programming recently and people said a good thing is to check on GitHub for projects with certain tags i.e. "good first issue", and there were some websites dedicated to finding them i.e. here. That seems fairly similar to what you're thinking launching here.
As it's a prototype, you might not have it fully fleshed out, but how would people add projects to the app? Would it be accessible via a browser?
I think this could be an amazing resource for bringing EAs together on projects, especially ones who don't have to time available to start something themselves or trawl through various places looking for something to do to help :)
Possible bug report: I tried to use the application but got 0% responses across the board after adding my experience and skills. I didn't see any kind of "submit" button.
On Firefox and Chrome, the search on past jobs did not work correctly for me (e.g. "research" produced no results even though "Research and Development Managers" was a job in the list), and I couldn't see a way to select any jobs. But I was glad to see ALLFED mentioned in your nice video!
This is currently just a prototype, with many many bugs. I've actually joined the team and EA CoLabs. Which is a proper application of the concepts here.
