Snapshot

LogBook Professor Workspace is a private multi-tenant classroom-management SaaS direction. It focuses on the educator workflows around academic records, organization boundaries, and low-connectivity use rather than presenting a generic dashboard as the product.

Architecture evidence

Next.js and React provide the application surface.
Supabase/PostgreSQL provide the data and service foundation.
Row Level Security uses org_id to keep organization data separated.
PowerSync supports an offline-first synchronization direction.
Property, security, and load tests are part of the repository's verification approach.

Why it matters

Education software is full of stateful workflows: a record has an owner, a class has an organization, and an offline edit must eventually reconcile with the server. The important engineering work is not the number of screens; it is making those states and boundaries explicit.

Current status

The repository is private and the public product story should remain architecture-focused. This case study documents the design direction and evidence without claiming a public deployment or a finished LMS.
