  • Text and sentiment analysis platform "SentimentScan"

    Python
    Created a service for automatic analysis of brand reviews on social media and review sites. The system detects "sentiment" (positive/negative), key topics, and generates summary reports.

    Tasks and Achievements
    Data Collection: Deployed a pipeline based on Scrapy that parses Twitter, forums, and review sites, collecting ~100,000 reviews per day.
    …
    Data Preparation: Used nltk and pymorphy2 for tokenization, normalization, and stop-word removal.

    ML Model: Trained a model based on sklearn (Logistic Regression + TF-IDF) for sentiment evaluation. Additionally, extracted key words and phrases (RAKE).

    Microservices and API: Divided the logic into several services (data collection, analysis, REST API for delivering results) that interact via gRPC.

    Results:

    Sentiment recognition with an accuracy of about 88%.

    The marketing and PR department quickly responds to negative mentions, increasing customer loyalty.

    Reports are generated automatically and updated every 2 hours, providing timely analytics.

    Technology Stack: Python (Scrapy, nltk, sklearn), Docker, gRPC, PostgreSQL, Elasticsearch (for fast text searching).

    Auto-click script for background interaction with games (AHK + AHI)

    Embedded Systems & Microcontrollers
    Development of a complex script in AutoHotkey for the game Foxhole, which runs in the background even when the window is minimized.
    Support for key combinations (Shift+LMB, RMB, action keys, etc.), interaction with the window via PostMessage instead of standard ControlSend/ControlClick.
    The script uses AutoHotInterception (AHI) to handle system keystrokes in the background without intercepting the main input.
    Ideal for automating routine actions in the game.
    …
    Also implemented:

    Automatic game window detection by title

    Flexible pause settings

    Minimalist structure with expansion capabilities

  • Personal Finance Management Platform "MoneyWise"

    Python
    Developed a desktop application in Python for analyzing and planning personal finances. The program allows users to track income and expenses, create charts by expense categories, and generate monthly reports.
    Used PyQt5 to create a user-friendly interface that works on Windows, Linux, and MacOS.
    Implemented data storage in SQLite, set up migrations, and automated backups.
    With pandas and matplotlib, created a block that visualizes income/expense dynamics and generates PDF or Excel reports.
    … For the confidential part of the data (e.g., passwords for bank accounts), used the cryptography library to encrypt records before saving them in the database.

    The program allowed users to generate monthly summaries twice as fast as traditional Excel templates.
    Ease of installation (single .exe/.dmg/.AppImage) and minimal hardware requirements.

    Technology stack: Python, PyQt5, SQLite, pandas, matplotlib, cryptography.
