The problem TEAMDER solves

Finding a teammate is a hell lot of a job for individual participants in Hackathon. We saw that happening at InOut this year when participants who did not have any team member found it difficult to participate. The Telegram Channel was filled with a message for Team and you still cannot be sure that you get the best member. Even during the start of the Hackathon, the participants struggled with finding teammates.
So, we thought of creating Teamder ('kind-of ' Tinder for Hackathon Teams).

We use Elo ratings for each individual participants to find the best member for them. Participants 'left' or 'right' swipe their preference like Tinder and the Matches get notified to form a team!

Challenges we ran into

The major part was finding an Algorithm and using it to get matching participants who could connect. We filtered participants based on Skills (Backed, Frontend, Mobile, Design and Blockchain) and then showed them to the user according to Elo Ratings.
