About Me
A proactive IT professional with a unique and accelerated career path. Started my commercial career at the age of 15 as a freelancer, which allowed me to accumulate deep practical experience even before completing my studies. Thanks to my high level of self-organization, discipline, and ability to quickly master new technologies, I effectively combined my studies at college (where I am the best student in the department and a teacher of algorithmization) with intensive project work and leadership positions. I am passionate about complex architectural tasks, from web services in Python to low-level optimization in Rust and Assembler. I work equally effectively both in a team and independently, always striving for a high-quality result.
In addition to commercial development, I actively participate in the life of the IT community: I am a contributor to open-source projects and took part in major global hackathons World's Largest Hackathon 2025 and Kiro Hackathon 2025.

Additional Information
Passion for IT I am deeply passionate about the IT field not only professionally but also as a hobby. Apart from software development, I enjoy working with electronics and system administration: I set up DNS records, create mail servers, and maintain computer hardware. This constant exploration helps me stay current with emerging technologies. Communication Skills People often assume that highly technical individuals lack strong communication skills, but in my case, the opposite is true. I attended a theater club in my early years, which helped me develop public speaking and presentation skills. As a result, I can clearly explain complex technical concepts, even to those with zero IT knowledge. Teaching and Mentoring I enjoy sharing knowledge, assisting team members, and teaching colleagues. I have successfully motivated and taught children (ages 7 to 15) the basics of IT, and I am even more effective when teaching adults. Providing training sessions and writing articles are also part of my skill set.
