Senior Frontend Developer / UI Tech Lead

Kyiv · $5000 · 7 years of experience · Upper Intermediate

I have excellent skills in prototyping large salable projects with rich UI architecture and complex styling systems. Experienced in Atomic design implementation and rendering performance optimization. Also I have experience as a lead developer. Despite the fact that I worked with AngularJS and ReactJS, usually, my main duty were to provide excellent UI/UX and mentoring for teammates. So my strengths are: HTML, CSS with various preprocessors such as SCSS / LESS, adaptive and semantic markup, Flexbox, CSS animation and effects, Bootstrap, font icons, cross-browser compatibility, the development of a modular architecture with a complex system of styles at the skin level. Also I have good experience writing JavaScript components using vanilla JS with support for the WCAG standard. Of course, I have worked enough with jQuery and some CMS such as Wordpress and Drupal, but I will never work on projects with these technologies. In addition, I have experience with HTML emails, structured Google markup, Webpack / Gulp, CVS (SVN / Git), task management tools (JIRA, Trello, Redmine), Photoshop & Illustrator (Zeplin), flexible methodologies such as Scrum and Kanban.

HTML5, CSS3, JavaScript, React, User Experience , English, SASS, Git, JSON, Adobe Illustrator, Adobe Photoshop

I live in the life-rhythm of modern technologies and try to regularly attend various conferences and seminars. Work experience in the world famous IT-company and development of features are presented at the international exhibitions. Experience on the lead developer position in the international team.

Important: If you are looking for a senior ReactJS engineer / architect, this is not about me. I focus more on the UI development and prefer to stay on this side of the FE responsibilities and will be happy to take part in any management activity. My expectation from a new position is a flexible schedule or the ability to work remotely or relocate with a competitive salary. I prefer to work with large projects and mainly with style architecture and UI prototyping but ready to take part in any other activities related to development or management.
