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).

Eugene B.

Java Developer

Russia - Tests: 5

Over the last 7 years I have been involved in several performance-sensitive projects using Java, including video surveillance solution and stock trade automation system. My core competency is performance optimization, and I'm seeking the opportunities to enhance your application to run as smooth as possible. I also would not mind designing said application from the ground up, with performance in mind, of course. Last, but not least, I would be delighted to practice Haskell.
