Java is my main language and I've spent the last 3-4 years working with it on a day to day basis. I have experience in writing large code bases using TDD (unit/integration/end-to-end + mocking) and have deployed Java Application Servers and other services written in Java. I've worked on RESTful web services (JAX-RS), JPA, Dependency Injection (Guice), Google Protobuf and many more.

I've spent the last year at my company learning and writing Scala for our front end web servers. I've had experience with using the Play framework along with Scala Test (for testing). I've also used Selenium webdriver to test the front end web application that is served as part of the Scala Play server.

I've spent the last year and a bit working on a front end web application written in Javascript with React JS. The first version was written using Fluxxor and was deployed as part of the Scala Play server (mentioned in my Scala expertise area). I am currently writing a second version of the front end using Redux to manage the state. I started this from scratch so it gave me the experience of starting a new project using React + Redux which allowed me learn an incredible amount about React + Javascript development. I hadn't done much Javascript before this (I have a little experience with Angular JS but that was a while ago), but I found I picked it up quite quickly and React + ES6 syntax has allowed us to easily write front end applications that can be maintained fairly easily.
