I've trained 50 JS developers to master React.js and React Native at Frontend Science (it's an educational company). I've been a speaker on few conferences: - React Renderer for your Smart home - React Fiber at React Kyiv - React Fiber at JSLab Open source projects I've worked on: - created React.js renderer for controlling smart home devices - created an integration library between Nightwatch end-to-end testing system and TeamCity continuous Integration. - made a contribution to Babel
