Frontend Engineer with 9+ years experience

I am mostly a Frontend engineer, and I have 9+ years of experience in the field; during my career, I moved from PHP+MySQL+JS to Node.JS+React/Angular/Backbone to mostly React and some Node.js. In almost every company I worked for, I had to learn some new language or toolset; I consider myself a good learner. I had a brief experience as a Lead Engineer. I'm looking for a front-end-focused role, but I'm open to working on full-stack again.
