Objective:
Architect and develop applications using Ruby on Rails.  I enjoy supporting applications throughout their lifecycle.

Relevant skills:
On the server: Ruby on Rails since 2007 (1.x to 5.x)
Databases: PostgreSQL, SQL Server, MySQL, Oracle (roughly in order of experience – since 1998)
In the browser: CoffeeScript, JavaScript (I have not yet made the jump to a recent EcmaScript, but it is on my list)
Vue, React, Angular (1 & 2), Backbone, underscore, jQuery, D3 (mostly light UI/UX with a couple of more complex applications)
CSS (SCSS) and HTML (HAML), Bootstrap
Clients: provide JSON apis.  Limited XML back in the day.
Services: Redis, Memcached (mostly just for caching – a little tricky stuff with Redis), limited Google maps, other external JSON APIs
OS: *nix since 1989.  I currently do all my development in Docker containers using MacOS as the host.
Source Control: Git since 2006 (I am a big fan of hub flow)
CI/CD: Jenkins (I believe in 1 button or no button deployment)
Deployment: Docker Swarm, Kubernetes, Heroku, AWS.  No bare metal deployment for a few years.
Phone: a couple of light iOS apps using native code
