I'd like to remake the whole app into a simple interactive dashboard.
- Use postgres on Heroku for data storage
- User upload will sync CSV entries with their data in the DB
- Implement user registration/login
- Still enable anonymous upload without the data storage - limit the dataset to one year or something
- Data will be processed on BE and fetched on FE, using some JS lib to display charts (chart.js, d3.js? Dunno yet)
