I've been freelancing for 4 years now and started off with full stack development in EmberJS with Ruby on Rails as a backend. A little over 2 years ago, I shifted to Elixir/Phoenix as a backend, and then, a year ago, to React as the frontend of choice.
Prior to that, I've worked full stack development jobs, mostly with a .NET backend.
I have extensive experience working on projects from initial creation to completion, as well as working remotely, in different timezones and with team mates with different backgrounds.
