Auto.ru (auto classifieds website) was acquired by Yandex in the late 2014 and I joined the project as a head of front-end dev team. I had to reorganize the existing team and to replace old php/jquery codebase with modern technologies. Responsibilities:

• Team (15-20 people) management: hiring new people, replacing team members, teaching, 1-on-1.
• Talking/teaching about new technologies to our team.
• Planning our work together with other teams (design, backend, testing).
• Choosing proper technologies, libraries, tools and incorporating them into our dev process. We replaced php with Node.js + Express and later we started migration to React and TypeScript.
• Writing tools and libraries if we couldn't find analogue in the open-source world. Like descript — data aggregation library and jpath — xpath-like query library.
• Code reviewing
• And of course writing a lot of JS/TS.

I worked on the project of replacing an old and slow Web 1.0 interface of Yandex.Mail (one of the biggest web mails in Russia) with a new, fast and shiny Ajax interface. My responsibility was to prototype a new tech stack for that project: server side JS (we used Firefox JS engine), working with XML and XSLT in a browser, new JS framework for SPA etc. And then with the rest of the team to finish the project using all of this tech. Later when we decided to replace XSLT I wrote XSLT-inspired template engine in JS — yate.

I developed a web component library (called Lego) aiming to unify web interfaces of all Yandex projects. And also I helped other teams to adopt the library.

I worked on the development of several big projects in Yandex using HTML/CSS/JS/XML/XSLT:

• Yandex.Money (payment system)
• Yandex.Photo (photo hosting and sharing service)
• Yandex.Video (video search and hosting service)

I worked as a html/css coder in several web companies.
