Experienced, versatile developer and analyst

I have an extensive background in developing web systems with a variety of languages. I work with a team at TriTrySystems so that we can help clients have a team of developers, not just a single person, which gives a reliable source of expertise to our clients and provides for additional developer resources if necessary. We are also available to do project "rescues" and/or QA, for when previous developers have not been able to finish projects, whether they be in PHP, Perl, Python, or Rails. I particularly enjoy projects involving complex machine learning, systems programming (e.g., kernels, device drivers, filesystems, etc) or functional programming (e.g., OCaml, Haskell, Scala, Erlang, Clojure, etc).

Web development and related design and dev ops. Rails/js/bootstrap etc

United States - Tests: 3 - Portfolio: 2

I am well versed in many open source technologies. I prefer to use ruby and javascript when they are a good fit, but am always up for finding better tools for the job. In my day jobs, I generally work on rails or javascript projects with a mobile-first approach. Lately I have been using rails more for backend tasks and using AngularJS for the frontend. I have more than a decade of *nix (linux mostly but even bsd and a little solaris) experience and I have been a regular daily user of ubuntu for the past 8 years so system administration with ubuntu is another strength of mine. I also set up mobile friendly websites of varying complexity and handle all hosting, both static and dynamic and with and without cms systems. I have worked extensively with locomotivecms and can also deploy the locomotive engine if you are looking to host your own cms site. Some other work I have done on odesk included shopify programming and using the shopify api as well as several months specializing in RETS (Real estate transaction standard).
