Spotify already has collaborative playlists — but not a playlist generator that builds a group playlist from everyone's individual listening history. ReWrapped does that: point it at a group, and it generates a shared playlist weighted by what the group actually listens to.
Tech stack
Frontend: React, Material UI, Jest. Backend: Node, Express, PostgreSQL. CI: SonarQube for static analysis.
Results
Built by a team of six under strict agile practice — two-week sprints, with a strong emphasis on shipping thoroughly tested, robust code over moving fast.
Optimization
The application works great. It looks horrible. That's next.
