Santa App [Secret Santa]

Problem

Secret Santa becomes fragile when couples, custom restrictions, previous matches and wishlists are spread across multiple channels.

Decision

I modeled rules as concrete transactional exclusions to keep the domain explicit and simplify how the draw is executed.

Challenge

Keeping participants, rules and multi-year history consistent when an event's membership changes.

Result

The application brings authentication, events, participants, rules, exclusions, wishlists and email notifications into one flow.
