Hi,

My name is Sergey. I'm a professional Front-end Developer with overall 4 years of experience in mobile and web applications development. I have been working with JavaScript, React, React Native on front-end side and Node.js, Express on back-end side together with MongoDB database. Also, I have an extensive experience in using Xcode and Android Studio IDE for IOS and Android applications development.

I’ve been working as a developer, and a team leader collaborating closely with designers, front-end and back-end developers, and project managers from overseas.

I’m a team player and I believe that the issue of collaboration plays a crucial role in a project. I like being in the process of creation, making things work and bringing new ideas into life. Every challenge I deal with I consider as an opportunity to get new knowledge and become better as a developer.

I’m a hardworking and responsible person who loves what he does.
