Full-Stack Developer
Passion for code, eye for detail
I am a full-stack developer with a lifelong passion for IT. For over 4 years, I have been building commercial web and mobile applications, ensuring that the code is stable and the user interfaces are polished and intuitive. In my work, I combine a fast-paced approach with a strong commitment to quality and architecture.
In my free time, I enjoy cycling, reading comic books, and developing my passion for game dev – from drawing and 3D modeling to creating projects in game engines.

Work Experience
SELLEO
Frontend Developer
Work on web and mobile applications across EdTech, AI, crypto, and HR - from delivering new features to developing and improving existing systems. The scope included building user interfaces, working with data, integrating with backend services, and making architectural decisions on the frontend side. In addition to implementing new functionality, a significant part of the work focused on maintaining code quality, refactoring, and ensuring scalability in production applications. Day-to-day work involved real-world problems: complex forms, dynamic data views, debugging challenging issues, and introducing changes without destabilizing the application.
- Development of applications using React, Next.js, and Astro
- API integrations and collaboration with backend teams
- Complex UI: forms, dashboards, data-heavy views
- Debugging and stabilizing production applications
