DeliMoney

DeliMoney is a Telegram-based service for people who share expenses with friends, family or travel groups. Users can create a group, add expenses, split them between people and see who owes whom, without having to keep everything in a spreadsheet or calculate it manually. The service also supports different currencies, tips, repayments and receipt photos, which can be turned into structured expenses automatically.
I built the system end to end, including the Telegram bot, WebApp, backend, database, payments, admin panel and production infrastructure. The project is designed as a real product rather than a demo, with tools for subscriptions, analytics, user management and ongoing operations.
