Smart Grocery & Expense Tracker with Telegram Login

I developed a lightweight web application that helps my family track purchases, analyze store prices, and optimize shopping lists.

The system uses Telegram authentication, so users can log in instantly without creating accounts or remembering passwords.

Key features:
• Quick receipt entry with stores, products, and categories
• Automatic price tracking across different shops
• Smart shopping list analysis that finds the cheapest store
• Shopping lists sent directly to Telegram
• Mobile-friendly interface for use while shopping

Built with modern technologies including SvelteKit, TypeScript, PostgreSQL, and Telegram Bot API.
