I'm really good at this, and have been doing it for a while.
Specialties include EmberJS, VueJS, and Ruby on Rails.
For longer-term engagements I will learn whatever tech is necessary, especially if it's closely related (React, Django, etc.) or cool (Elixir, Clojure, etc.)
Not an expert, but excited to get involved.
I'm particularly interested in neighborhood planning, sustainable communities and land use, and health.
Reach out to me if you're doing cool stuff - especially if you're in the Austin area.
