  • Telegram bot with integration of local SQLite database

    Bot Development
    Telegram bot with integration of local SQLite database — example of freelancer's portfolio work in category Bot Development
    I developed a stable Telegram bot in Python using the telebot library. The main feature of the project is the integration of the built-in sqlite3 module for working with a local relational database. The program can automatically create tables, write, update, and query data using direct SQL queries. This is ideal for projects where long-term storage of user profiles or logging actions is needed without losing speed. I also set up a security architecture, so all configuration API tokens are completely moved to hidden environment variables in a .env file. Database connections are opened and closed correctly, which protects the files from locking under high loads.

  • Information Telegram weather bot with OpenWeatherMap integration

    Bot Development
    Information Telegram weather bot with OpenWeatherMap integration — example of freelancer's portfolio work in category Bot Development
    Developed an interactive bot that provides detailed weather forecasts for any city in the world in real-time. The bot automatically adapts the interface language and sends a beautiful visual report to the user.

    Technical features of the project:

    … Programming language: Python (telebot library).

    Integration with external service: asynchronous/synchronous requests via the requests library to the OpenWeatherMap API.

    Data processing: parsing complex JSON responses, obtaining extended parameters (temperature, feels like, humidity, wind speed).

    Dynamic media interface: the bot automatically generates and sends a photo card with the official weather icon directly from the server.

    Error protection: network requests are protected by timeouts and try/except blocks in case of internet failures.

  • Multifunctional Telegram bot for currency conversion

    Bot Development
    Multifunctional Telegram bot for currency conversion — example of freelancer's portfolio work in category Bot Development
    Developed a convenient Telegram bot that allows users to instantly transfer amounts between different currency pairs. The bot supports both fixed popular directions and manual input of any world currencies by the user.

    Technical features of the project: Programming language: Python (telebot library).

    … Data handling: Integrated the currency_converter module for accurate and up-to-date rate calculations.

    Step-by-step scenarios: Implemented complex dialogue logic through register_next_step_handler, guiding the user from entering the amount to selecting the result.

    Security and stability: Inline buttons are automatically removed after being pressed, preventing the user from breaking the logic with repeated clicks on old messages.

    Interface optimization (UX): Implemented automatic replacement of commas with dots when entering numbers, protecting the program from accidental user errors.
