🏆 People's Choice — Sustainability Showcase 2026 (UN SDG 4 & 8)
An academic-integrity learning platform. Instead of storing snapshots of a student's work, it records the sequence of edits so the work can be replayed step by step — showing whether it grew gradually or appeared all at once.
- Designed an event-sourcing model (an append-only log of edit operations) that powers step-by-step replay.
- Designed a tool-platform contract so independently built browser tools plug in through one published API.
- Designed the database schema and a role-based access-control model with resource-scoped permissions.
