The story
An app meant to bring the club something nobody else has — community through digital.
A complete platform built for a planned billiard club: a native app for members, a dashboard for staff, a .NET backend. The club is still in planning.
Worth noting
A planned billiard club needed a complete operational platform — for members to reserve tables, sign up for tournaments, and track their matches; for staff to manage tables, tournaments, billing, and league seasons. All of it from day one.
Three components. .NET, with a full domain model (tables, reservations, tournaments with bracket visualization, seasons, table-session billing, user accounts, employees). A Next.js dashboard for staff. A native iOS + Android app (Expo + React Native) for members. Identity through Keycloak, so member authentication, SSO between apps, and staff role management were enterprise-grade from the start. Centralized logging through Seq, so every incident can be found quickly.
Modules & surfaces
We approached the system as a long-running project. We chose Keycloak because member authentication isn't trivial (SSO across apps, OAuth flow for the mobile app, password reset, role-based access) and we didn't want to reinvent it. We chose Seq because running a club system means quickly answering "why didn't this member's reservation go through" — without centralized logs, that would be an hour of digging through server files. Clean Architecture for the API because we expected long iteration cycles, with new features arriving over the club's years of operation.
Built, tested, ready for production. The club hasn't opened, so the system isn't yet in actual use. The project stays in the portfolio as evidence of how we approach systems intended for long-term use — the architectural decisions still stand, even though the launch hasn't happened yet.
