    Automation of marketing data collection (High-Speed Async Scrape)

    Python
    Automation of marketing data collection (High-Speed Async Scrape) — example of freelancer's portfolio work in category Python
    Development of an adaptive tool for data collection of any complexity. The system is designed to work with various types of web resources: from simple landing pages to multi-page catalogs and dynamic platforms. The main focus is on transforming unstructured HTML code into clean, business analytics-ready data.
    Technical capabilities (Senior level):
    Versatility of sources: Algorithms are configured to extract data from any structures: marketplaces, social networks, technical specifications, or news.
    High speed (AsyncIO): The use of non-blocking requests via aiohttp allows processing hundreds of pages simultaneously, minimizing wait time.
    … Working with Big Data: Automatic serialization of results in JSON format, allowing easy import of data into databases, CRM systems, or Excel.
    Adaptive parsing: Use of BeautifulSoup4 for deep analysis of the DOM tree and extraction of specific meta-data (titles, prices, articles, descriptions).
    Mobile-Ready: The script is fully optimized for execution in the Termux environment, allowing parsing to run 24/7 directly from a mobile device or lightweight server.
    Result: The client receives not just a script, but a full-fledged data conveyor. All collected data is automatically saved in a structured file (parsed_data.json) in the device's internal memory for immediate use.

    AI bot infrastructure: RAG + Vector DB + Asyncio

    Python
    AI bot infrastructure: RAG + Vector DB + Asyncio — example of freelancer's portfolio work in category Python
    Demonstration of the core operation of my AI agent (real-time launch log).
    The screenshot shows the system initialization process:
    1. [SYSTEM]: The environment runs on Python 3.12.12 in asynchronous mode (Async/Await) — maximum request processing speed.
    2. [MEMORY]: Connection to the Pinecone vector database (index 'client-knowledge-base'). RAG mode (Active) is enabled, allowing the bot to respond accurately based on your documents rather than inventing facts.
    … 3. [NETWORK]: Checking connection to OpenAI API. A latency of only 142ms has been recorded — instant bot response.
    I am deploying this solution for clients who need a smart, fast, and stable bot for business.

    Beryl AX traffic monitoring and management system (OpenW

    Python
    Beryl AX traffic monitoring and management system (OpenW — example of freelancer's portfolio work in category Python
    Development of an intelligent access control system for GL-iNet routers (Beryl AX). The project is implemented as a standalone solution, operating directly in the Termux environment on Android and interacting with the router in real-time via API.

    Technical challenges and solutions:
    - Compilation on ARM64: The pydantic-core kernel was successfully compiled on the Galaxy A36 mobile device, which required 100% CPU load and specific configuration of the system environment.
    … - Smart Traffic Monitoring: An algorithm for filtering background traffic (threshold less than 50 KB/s) was implemented to accurately account only for the user's active screen time.
    - Asynchronous architecture: The use of the aiogram 3.x library allowed for instant bot interface response while continuously monitoring network activity in the background.

    Results (User Stories):
    - Dashboard: A professional interface with real-time usage limit status and quick session extension buttons.
    - Kill Switch: A function for instant complete blocking of internet access (Panic Mode) through direct commands to the router's firewall.
    - Automation: The system is deployed as a background service in a tmux session, ensuring stable operation 24/7 without the need to keep the terminal open.

    Automatic data collection: Integration with external supplier APIs to obtain current price lists in real-time.
    Intelligent processing: Implemented flexible business logic: dynamic price recalculation considering currency fluctuations (USD/UAH) and customizable margins.
    … Visualization and control: Created a professional console interface (CLI) with interactive tables and product status indicators (In Stock / Out of Stock) for operational monitoring.
    Reliability: The system is equipped with an operation logging module and automatic data backup to prevent losses during failures.
    Technology stack (Stack)
    Language: Python 3.12 (Core logic).
    Libraries: Rich (Professional CLI/UI), JSON, Requests.
    Database: SQLite (Local persistent storage).
    Automation/DevOps: Bash Scripting, Git/GitHub, Termux/Linux environment.
    Security: OAuth 2.0, Environment Variables (.env).

    Autonomous CRM system in Telegram with Google Sheets integration

    Python
    Autonomous CRM system in Telegram with Google Sheets integration — example of freelancer's portfolio work in category Python
    Task: Create a reliable lead collection system that operates 24/7, does not require monthly payment for CRM, and eliminates data loss during internet outages.
    What has been implemented:
    Hybrid database. Leads are instantly sent to Google Sheets (for manager convenience) and duplicated in a local database (for reliability).
    Data validation. The bot checks phone numbers, cleans them of unnecessary characters, and formats them uniformly.
    … Admin panel. The owner manages the bot through a hidden menu: viewing statistics, checking server logs, and exporting the client database to a CSV file with one click.
    Fault tolerance. A Watchdog system has been implemented: if the bot process stops due to a server error, the script automatically restarts it.
    Protection against spam and queues. A finite state machine (FSM) has been implemented so that the user cannot break the bot's logic with chaotic clicks.
    Result: A fully autonomous tool for small businesses, replacing the manual labor of an administrator.
    Technology stack: Python, Google Sheets API, SQLite, Telegram Bot API.
