My hard skills are based on knowledge and experience with Front-end: ● React, Redux, Mobx, jQuery; ● CSS/SCSS, Tailwind, Material-UI, Styled Components, Emotion, Bootstrap, ZURB Foundation for Emails (responsive emails); ● Next.js: Pages and AppRouter engines. I provide a pixel-perfect and well-tested responsive design layout.

I prefer a declarative approach, well structures, and clean code. I love to learn new and share knowledge. Arrange things - it's my weakness. I'm completely self-dependent, high responsible and reliable, attentive to the details, good in business and smart. I like clever challenging tasks and open to new opportunities.
