My work is not just a job, but also a hobby and a big part of my life. I spend a lot of my free time to learn about recent updates in a front-end development. I know what I can use right now and what I will able to use in the next few month. The code I write is always in line with best practices, guidelines and strict rules of linters (ESLint and Stylelint, to be exact).
Also, I have an experience of leading a small front-end team. Most of the time I work remotely, so I know how to get things done on time.
I do care about typography / UI / UX and the appearance of the project is really important (along with good performance and optimized markup/styles). Also have an experience in Quality Assurance (year and a half of full time job) — every little piece of project is matter to me.
