CV
Hi! My name is Yegor, and I’m a developer with experience in creating apps and games. My main tech stack includes Python and C++, but I also work actively with React to build modern and user-friendly interfaces.
I enjoy developing projects that solve real-world problems and bring value to users. Here are a few of my key works:
- SPTON — a mini app (clicker) on Telegram with a space theme. It combines a powerful Python backend with a user-friendly React frontend to deliver an engaging gaming experience.
- PyDeskLink — a desktop application for remote computer administration built with Python, designed to make device management secure and straightforward.
- YumBot — a Telegram bot for finding venues in Kyiv. Users can not only discover the best places but also leave reviews to share their experiences.
- Arkanoid on C++ with SDL2 — my version of the classic arcade game. In this project, I refined the gameplay, optimized graphics, and controls to create a fun and captivating game.
I’m always on the lookout for new and exciting challenges where I can apply my skills and grow. If you’re looking to bring a creative project to life, improve an existing app, or develop a unique product, I’d be happy to help!
Feel free to reach out to discuss the details!
