This repository is part of broader Food Tracker ecosystem

A daily automated pipeline that scrapes food prices from major Slovak retailers and stores them in a PostgreSQL database for price tracking and analysis.

• Automated Daily Scraping: Runs automatically every day at 7:15 AM CET/CEST on a local machine
• Parallel Processing: Async scraping with retry logic for reliability
• Data preprocessing: Data is processed before being uploaded to DB
• Database connection: Uploads data to Supabase DB
• Telegram Notifier: Sends outcome message to Telegram

The scraper collects data from cenyslovensko.sk, Slovakia's government-backed price comparison portal which was launched in June 2025.
