About Me

I am a full-stack developer with over six years of experience, specializing in building modern web applications. On the front end, I work with React and Next.js; on the back end, I develop with Node.js (Express, NestJS) and MongoDB. I’m passionate about designing scalable system architectures and implementing cloud solutions.

Experience

I have worked with startups, software houses, and large corporations across various industries, helping them build scalable applications and solve complex technical challenges.

My approach combines deep technical expertise with an understanding of user needs, resulting in functional and user-friendly products.

Hobbies

Outside of programming, my passion is astrophotography. I love capturing the beauty of the night sky and sharing it with others.

This hobby has taught me patience and precision—qualities that are equally important in my coding work.

What Sets Me Apart

I communicate complex concepts clearly and thrive in international teams, quickly adapting to changing requirements.

I always prioritize code quality and performance — and I hold myself to high standards regardless of project size.
