Hello!

I have experience with Supabase/PostgreSQL focusing on performance and RLS. I am ready to take on the entire backend of your application: from setting up pooling to transferring logic from AppSheet to the database and writing RPC functions.

What I will do:
1. Enable and configure pgBouncer (pooled connection) --> we will resolve MaxClientsInSessionMode
2. Optimize the schema and indexes (levels, groups, schedule, attendance, grades).
3. Move calculations to SQL views (vw_schedule_today, vw_teacher_schedule, vw_students_in_group) — AppSheet works only as UI
4. Configure RLS for Admin/Teacher roles with full data isolation
5. Write RPC/triggers for bulk operations (cloning/moving schedules, auto-updating colors/statuses)
