Douglas H.

Ruby developer

United States - Tests: 7

Ruby has been my main language for a number of years now. I also use Javascript frequently (on the client and server), and Java and Perl when the need arises. I use Ruby on Rails for a number of projects, but a large part of my Ruby work is outside of Rails, as ruby is now my primary language. I have a great deal of SQL experience but have been using noschema databases for most new projects for a couple of years (specifically MongoDB). I have been working in a freelance environment for a number of years, and have a multi-machine linux-based network with constantly running infrastructure suited to tackle any task as it arises. I do a reasonable amount of system administration for my own pleasure or in the cloud for clients, and also run and administer client production deployments myself.
