gitRizz.ai

Inspiration

We realized that a person’s GitHub says more about them than any dating profile ever could—commit history, README vibes, even that one cursed 2 AM push. So why not let the code do the talking? With gitRizz.ai, we’re turning repositories into relationships, because nothing says “soulmate” like burnout and a mutual obsession with clean code ❤️

What it does

gitRizz.ai is a Hinge-style matchmaking platform that curates GitHub profiles to find the most optimal matches - all you have to do is login with Github! We generate vector scores for each user, combining numerical metrics (commits, contributions, PRs) with contextual analysis (commit messages, READMEs, bios, profiles) to get a well-rounded view of their personality from both their technical contributions and textual expressions of themselves. Using vector search, we calculate similarity scores between users, ensuring meaningful connections. Lastly, we used OpenAI to generate personalized feedback for each profile since a lot of these Github profiles can have a lot of information all at once. If two users mutually swipe right, they can chat and collaborate—professionally or romantically!

How we built it

Backend: We used the Github API and beautiful-soup to scrape most public data from a user’s profile—including their picture, READMEs, bio, and so on. We consolidate all the quantitative contributions of the user (number of contributions, commits, pull requests, PRs, etc.) as well as an analysis of their textual contributions such as the commit messages, READMEs, and PR content. Using OpenAI API, we are able to generate an 6-dimensional vector representing their characteristics ranging from commitment to collaboration style. Finally, using a cosine-similarity matching algorithm, we are able to generate an list of potential matches to show a specific user.

Frontend: Firebase + Github authentication, and from there, it was all React + JavaScript + Flask.

Challenges we ran into

For future scalability, it is important to minimize expensive API calls. At first, our output was generated way too slowly as calls were made repeatedly. Instead, by caching users vectors, we are able to reduce computation significantly. In the future, we would likely be able to utilize an ML algorithm that can perhaps avoid such calls for certain users all together and instead infer potential matches more indirectly (ex: A and B are a good match and A and C are a good match, so maybe B and C are a good match.)

Also, deciding what metrics to hone in on was a challenge, one that we are still working on.

Accomplishments that we're proud of

We wanted the UI to highlight just how much of the work we do for you - after all, all you do is login with Github and we calculate everything from there. Thus, the interface had to be simplistic, modern, yet easy to understand and use when it came to finding matches and prospective candidates. Mapping this out and narrowing down on a design was difficult but worthwile.

Also, we’re proud of simply ideating this project, which is the perfect balance of silly and serious. Beyond classes and random cool hackathon encounters, there really isn’t a systematic tool for meeting devs with a similar vibe as you!

What we learned

Designing for scale from the beginning is important! Caching user data from the start would’ve made life so much easier.

Also, sometimes, the best ideas come from silliness—this was inspired by Valentine’s Day!

What's next for gitRizz.ai

Adding more metrics on which to match people on. Adding more text and video prompts. Allow users to filter by platonic or romantic, sexuality, distance, etc. Reward and boost users who contribute to open-source repos, are rated well by peers, etc. Building out the chat + post-match interface. We wanted to focus on profile curation + statistics, so didn't implement this portion for the hackathon.
