Intro

I specialize in full-stack, API, and test-driven development of Ruby on Rails, Elixir, and JavaScript applications. I regularly contribute to open source when I find opportunities to fix or improve functionality and quality of software I use. I am looking to apply my agile product development skills to make long-lasting impact by improving software experience for all.
