I will create a bot using aiogram + aiohttp for parsing OLX, RST, Auto.ria. Each user saves their filters (price, region) in PostgreSQL, new ads are checked via cron and sent to the chat. Scaling through asyncio to handle the load with many users. Question: how often to check for new ads, every 5 minutes or less frequently?
