United States - Last active: 02/04/2012 - Tests: 10

I take periodic jobs on Odesk to keep my skills fresh and to gain an direct understanding of problems clients are experiencing. I enjoy finding and fixing high-level technical problems that others cannot solve. Most of my experience has dealt with web applications, which have many moving parts. Finding and fixing problems in this space has required me to learn a broad-based group of skills, including basic programming, SQL and Oracle databases, IIS and Apache web servers, middleware based on Java and .NET, and the networking devices that wrap around it, such as load balancers. I can help you in any of those areas, including problems of crashes and poor performance. If you wish to review my skills in detail, my always-updated resume is available here: http://www.linkedin.com/in/cosjef
