Description

Korisu is a Telegram ordering bot built for a sushi restaurant in Strasbourg, France. Customers browse the full menu by category, view individual dishes with photos and pricing, manage a cart, and place delivery or pickup orders — all without leaving Telegram. Confirmed orders are pushed in real time to a private Telegram group for the restaurant team and logged to Google Sheets.

My Role

I built this bot from scratch as a freelance project for a local sushi restaurant in Strasbourg. The goal was to let customers order directly through Telegram, removing friction from third-party apps and giving the owner full visibility over orders in a channel and spreadsheet they already used.

Designed and built the full bot using Python and aiogram 3, with FSM-based conversation flows for menu browsing, cart management, and multi-step checkout
Implemented multi-language support (EN, FR, UK, RU) with a custom i18n layer
Integrated Google Sheets API to log every order automatically for the restaurant owner
Built a real-time order notification system that posts structured order summaries to a private Telegram group for the restaurant team
Deployed on Render with a Procfile and nixpacks configuration
