Lily SportOS: a SaaS platform for sports clubs
Lily SportOS is my own product. It helps sports clubs manage athletes, competitions and payments in one place instead of spreadsheets, group chats and paper.

Real interface: the tatami judging console and the athlete app in Telegram
The problem
Sports clubs run on spreadsheets, messengers and paper logs. Payments are tracked by hand, athlete data is scattered, and organising a competition takes weeks. They needed one system that covers all of this and works for many clubs at once.
What I built
- A multi-tenant architecture: every club gets its own workspace with separate data, settings and roles.
- Online payments via Monobank Acquiring with automatic status tracking.
- Tournaments, including events for several clubs: brackets assigned to tatami, a judging console with timer and points, and a scoreboard for spectators.
- Athlete passports with history and achievements.
- Attendance tracking and club statistics: athletes, trainings, revenue.
- Automatic Telegram notifications: training reminders, payment debts, birthdays.
- An admin panel for club managers and memberships for fitness clubs.
- A Telegram Mini App for athletes and coaches in two languages, with nothing to install.
- Infrastructure on my own VPS with Docker Compose.
What this means for you
I bring the same approach to client projects: thought-through architecture, payment and messenger integrations, a usable admin panel and a stable deployment. If your business runs on spreadsheets and manual work, that can move into a system that runs on its own.
What it looks like
