Front end developer

About

I am a Full-stack developer with focus on the front-end and over 6 years of experience in this area. I was working commercially with most top tech stack technologies React, Vue, Angular on a front-end and Express, Nest, Meteor, Mongo on a backend. For the last 3 years I am mostly focused on development using React. I try to do my best every day and develop myself and my skills diligently. I try to be enthusiastic about the work approach and technologies used. Always interested about new solutions but try to keep balance between innovations and reliability. I am always willing to provide reliable support and implement high quality software for a developed product .

Key skills:

• Good understanding of Javascript core

• Ability to write code on the Frontend and on the Backend

• Ability to clearly understand project goal, improve it and put attention into smaller details
