Job 5 of 13
Developed a high-performance microservice for monitoring car sale advertisements on the largest platform in Poland — OLX.pl and otomoto.pl. The system is designed for professional car selectors and resellers, where the speed of information retrieval is a decisive factor.
Key functionality:

Instant notifications: The bot detects a new advertisement within the first minutes after publication and forwards it to the client's Telegram channel.

Deep filtering: Support for 51 car brands with the selection of specific models, voivodeships (regions), price ranges, and year of manufacture.

Scalability: The architecture allows servicing dozens of independent clients simultaneously. Each user's settings are completely isolated.

Stability 24/7: The project is packaged in a Docker container and deployed on a VPS for uninterrupted operation.

Smart anti-spam: An individual database for each user excludes the resending of the same links.
