  • Telegram bot for collecting feedback

    Bot Development
    Stack: #python #fastapi #aiogram3

    Connecting two Telegram bots in one script. The first receives feedback from the user and forwards it to the second bot. The second bot then sends it to a separate moderation chat and, after a choice ("Publish" or "Ignore"), either publishes it in the appropriate thread of the general chat or ignores it.
  • User information parser from LinkedIn with GUI

    Data Parsing
    The application was created upon request for parsing open information from the social network LinkedIn.

    Application language: pure Python.

    Working mechanism:
    • The application logs into the LinkedIn website using the Selenium web driver (the first time it creates a cookie to simulate using the site as a live user);
    • Then the application takes information from the customer's Google Sheet in the form of a link to the user profile from the row specified in the ID field.
    • From the user's page, the application extracts the necessary information, and upon completing the traversal of all links, it saves the collected data to a csv file, sends it to Google Drive, and adds information with a link to the file in Google Sheet.

    Additional features:
    • Human action simulation to secure the LinkedIn account (navigating through specified links at random times, timers for staying on the page, timers for waiting for the page to load);
    • Waiting for CAPTCHA completion by the user;
    • Batch processing (sequential processing of more than one link without user intervention);
    • Sending notifications about atypical errors via email (for prompt response and resolution of emergency situations);
    • Update server and internet-based updates;
    • Interface customization.

    Possible adaptation to your requests.

A top-level professional!
I want to thank the freelancer for the incredibly high-quality and responsible work on my complex project. From the very first day of collaboration, I felt that the project was in reliable hands.

Stability and quality: The final product works perfectly, quickly, and without failures. Everything was implemented clearly according to the specifications, but even more!

Uninterrupted communication: The specialist was always available, promptly answering all questions and making adjustments. It felt like working not with a remote contractor, but with a part of the team.

A huge number of revisions. I had countless wishes and corrections during the work. The contractor, with true patience and understanding, made ALL the necessary changes, never objected or rushed.

What impressed me the most was that the specialist not only did what was asked but also proposed solutions, seeing where improvements could be made for better reliability or convenience for the end user. He truly contributed many valuable enhancements that I hadn't even anticipated!

An ideal performer for complex projects. I recommend!

This was a non-trivial project and I, as is often the case with clients, did not fully know what I needed myself. Serhiy proposed a non-trivial solution, explained why it was the optimal choice, implemented it, and then provided final explanations. I am pleasantly impressed both by the quality of the work and by the attitude towards the client and communication. I hope we will work together again.
