Engineering highlights

1. 1

   Designed a calm, warm identity in butter yellow, dusty blue and cream with serif display type, deliberately unlike clinical edtech dashboards.

2. 2

   Built a block based lesson model where every block renders a faithful canvas preview, edits inline and exposes structure through an inspector panel.

3. 3

   Added live validation and a publish checklist so the publish action always states exactly what is outstanding.

4. 4

   Layered AI actions on top of authored content rather than replacing it: generate, differentiate, convert and expand all operate on the teacher's own blocks.

5. 5

   Implemented curriculum extraction so an uploaded CAPS document auto maps objectives into the weekly planner grid.

6. 6

   Made the whole delivery path offline capable, with preloaded packs and reconciliation on reconnect.

7. 7

   Sized touch targets and layouts for Smart Boards and tablets first, then scaled down responsively to phones.
