Projects .
1. Jewel Maze Game (OOP Course Project)
Technologies: C#, .NET (Console Application)
Developed a console-based maze game where players navigate through levels,
collect jewels, and solve puzzles, applying core Object-Oriented Programming
principles.
Implemented key game mechanics such as player movement, collecting rewards,
and navigating through obstacles like doors and keys.
The game supports user registration and progress saving, allowing players to
resume their game after restarting the application.
Designed the game with extensibility in mind, laying the foundation for future
upgrades, including custom level creation and graphical user interface integration.

2. Information System for Knitted Product Inventory (Database Course Project)
Technologies: C#, WPF, MS SQL, .NET
Developed an information system called "VsInside Management" aimed at
optimizing and automating production processes in a knitting company.
Designed and implemented a relational database using MS SQL to manage
inventory, orders, and production batches.
The system allows users to generate reports, track production, manage inventory,
and process customer orders efficiently.
Key features include data filtering, sorting, adding, editing, and deleting product
information, as well as generating statistics on production and sales.

3. Telegram Bot for Service Automation (Independent Project)
Technologies: Python, SQLite, Telegram Bot API, Google Drive API
Developed a fully functional Telegram bot to automate services for users based on
role management (client, manager, owner), allowing for individual user experiences and
controlled access to specific features.
 Integrated secure access management with unique keys, ensuring that only
authorized users can access specific content or features.
Implemented user authentication and role-based menus, dynamically generating
available options based on the user's role (client for basic access, manager for content
management, owner for full administrative control).
Designed and managed an SQLite database for tracking user interactions,
managing user roles, storing keys, and handling access rights, ensuring efficient data
retrieval and storage.
Integrated Google Drive API for file management, allowing the bot to securely
deliver files to users based on their access rights, without exposing direct download
links.
Key features include:
 Role-based access control: ensuring each user has a customized interface and access
level.
 Access keys: generated and managed through the bot for secure access to specific
content.
 File management: integrated with Google Drive for handling and securely
delivering files.
 Error handling and validation: ensuring smooth user experience with robust
validation of inputs and proper error messaging.
 Scalability: designed with flexibility for easy extension, allowing future expansion
with new roles or content.

4. Website for Gadget Accessories
Technologies: PHP, MySQL, HTML, CSS, JavaScript, Google Sign-In API, third-party
logistics API
Developed a platform focused on selling gadget accessories, including phone cases,
decorative charms, and charging cables.
Implemented a user registration and authentication system, allowing users to create
accounts, log in, and manage their orders. Users can register manually or via
Google Sign-In.
 Integrated third-party logistics API to provide users with real-time shipping options and
order tracking. This allows users to select their preferred shipping method and monitor the
status of their deliveries.
Designed a guest shopping cart feature, where unregistered users can add items to the
cart, with data stored in sessions.
For registered users, cart data is stored in a MySQL database, allowing users to return
and complete purchases later.
Developed an order placement and tracking system with full shipping integration.
Built an administrative panel for managing products and orders.
Created a responsive frontend using HTML, CSS, and JavaScript, with features like
category browsing, product filtering, and search functionality.
Used PHP for server-side logic and MySQL for data management.

5. Server for Managing User Data (Lab Project)
Technologies: Node.js, Express.js, Sequelize, MS SQL

Developed a backend server using Node.js and Express.js for managing user data and

implementing CRUD operations.

Utilized Sequelize as an ORM to simplify database interactions and ensure scalability.

Designed a secure authentication system and implemented robust data validation on the

server side.

Integrated RESTful APIs to enable efficient data exchange between the server and client

applications.
