    Parser Auto.ria.com + Telegram Bot (Monitoring new cars for 10

    Bot Development
    Parser Auto.ria.com + Telegram Bot (Monitoring new cars for 10 — example of freelancer's portfolio work in category Bot Development
    Developed a comprehensive system for auto selection and resellers. The bot monitors the website Auto.ria.com 24/7 and sends notifications about new cars faster than the official application.

    Functionality: Instant notifications: Messages arrive in Telegram 10-30 seconds after the announcement is published on the site. Flexible filters: The user can subscribe to a specific Brand, Model, Year (from/to), Price (from/to), Region. Stability: The system operates on servers 24/7, bypasses bot protection (Cloudflare/WAF), emulates a real user. Convenience: A full menu with buttons, pagination, and subscription management directly in Telegram.

    … Technical part:
    Python 3.11 (Asynchronous)
    PostgreSQL (User database)
    Docker (Containerization)

    I can implement a similar parser/bot for OLX, Prom, Rozetka, eBay, or any other platform according to your needs.

    Development of complex Telegram bots: Steam price monitoring + Admin panel

    Bot Development
    Development of complex Telegram bots: Steam price monitoring + Admin panel — example of freelancer's portfolio work in category Bot Development
    Developed a comprehensive Telegram bot for automated price monitoring on the Steam marketplace (CS2 Skins).

    The project is implemented as a full-fledged microservices application that operates 24/7, processes thousands of requests, and instantly notifies users of price changes.

    … TECHNICAL STACK:
    • Language: Python 3.11
    • Framework: Aiogram 3.x (full asynchronous)
    • Database: PostgreSQL + asyncpg (high performance)
    • Parsing: aiohttp (non-blocking requests) + Anti-ban system
    • Infrastructure: Docker & Docker Compose (containerization)

    PROJECT FUNCTIONALITY:
    1. Notification System (Price Alerts): A separate background service (Daemon) monitors the market and sends alerts when the price drops below the desired level.
    2. Inventory Analytics: Assessment of the total value of all Steam inventory via a link to the profile (takes into account the USD/UAH exchange rate).
    3. Trader Portfolio: Tracking investments, calculating PnL (profit/loss) in real-time.
    4. Bypass Protection: Implemented User-Agent rotation and a system of "smart" delays to bypass Rate Limiting from Steam.

    Source code and architecture:
    The complete project code is available on my GitHub (link below). There you can also view the ER diagram of the database and the structure of the microservices.

    OLX Price Tracker — Competitor Price Monitoring System

    Data Parsing
    OLX Price Tracker — Competitor Price Monitoring System — example of freelancer's portfolio work in category Data Parsing
    Developed an autonomous Telegram bot for monitoring prices on the OLX.ua marketplace in real-time (24/7).

    WHAT THE BOT CAN DO:
    — Automatic monitoring: The script checks the product price every hour.
    … — Bypassing protection: Data parsing directly through JSON (resistant to changes in the website layout).
    — Instant notifications: Sends messages in Telegram as soon as the price drops, calculating the difference (discount).
    — Human imitation: Uses User-Agent rotation so the website does not block requests.

    TECHNOLOGIES:
    Python 3, BeautifulSoup4, Requests, Telegram Bot API.

    APPLICATION FOR BUSINESS:
    This script can be adapted for tracking competitor prices, monitoring product availability, or finding the best deals on the market.
