As a full stack developer using Angular.js (later React) and Ruby on Rails, I helped this mental health startup grow from 5 to 40 people.

An asynchronous, web-based chat with no JS at all (by abusing the http protocol + css). Built to probe the limits of webapps.
A humorous, but functional, url shortener using AWS Lambda and no datastore in Python.
