Steven J. Agency Contractor

Experienced, versatile developer and analyst

United States - Tests: 10

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).
