Web App Backend Development

I'm seeking a developer to finalize a web app designed with Canva Code that will be used on an individual Microsoft site. The app is intended for me (a classroom teacher) to record student behavior data. This app will only be used by me so there is no need for user ID, etc.

Key Requirements:
- Review and edit existing code for optimization.
- Design and implement a back-end system (can use Supabase or similar) to:
- Store behavior data (positive and negative) for students (divided by class). Classes, students, and behaviors should be able to be edited/modified or deleted as necessary (this is included in the code)
- Retrieve data for generating reports and searching records (behavior for a single student, reports on a specific behavior).
-Generate alerts when a behavior has reached a specified threshold


Ideal Skills and Experience:
- Proficiency in web app development.
- Background in backend development.
- Experience with database design and data retrieval methods.
- Familiarity with code review and optimization.

Looking for someone who can ensure the app is functional, user-friendly, and reliable.

Again, this is for a single teacher so hoping this project is simple and quick! :)
