Heide Masters
Plan and follow darts tournaments live: group stages, brackets, scoring, player statistics and cost planning. Available on the web and Android.
The problem
A darts tournament needs more than a schedule: registrations, callers, scores and tournament progression have to stay in sync during play, including on phones.
My contribution
A personal product covering application design, React development, data modelling, role-based access and deployment. Organisers, players and spectators have distinct tasks and views.
Technical decision
Every dart is recorded individually. Scores produce the final result, which feeds into the bracket. A caller assignment determines who can score a match, and undo operations must correct that same state.
Implementation
React and TypeScript power the interface; Supabase provides authentication, PostgreSQL and live updates. The mobile caller records singles, doubles, triples, bull and misses. Tests cover permissions and core tournament workflows.
Outcome
A published web app with group stages, brackets, individual-dart scoring, player statistics and cost planning. An Android version wraps the same web application with Capacitor. Screenshots use demo data.
Limitations and trade-offs
A live app needs to account for lost connections, corrections and concurrent use. The implementation is verifiable; I do not claim saved organiser time or real participant numbers without measurements.
