Have experience in:
GameDev - my current job is game creation. I am working with graphic librarie PixiJS. And its React-wrapper react-pixi-fiber. Also in work use other react-stack. In personal projects did using VueJS and its tech stack, wrote games at *vanilla* js.
Frontend - like gamedev, only with html/css. I know BEM methodology, css preprocessors like SASS, LESS. Know styled-components, but love reshadow. Favourite module bundler - webpack.
REST API, NodeJs (koa, express), sockets, sql/no-sql db.
