Jack of all trades, master of a few, member of Experts Exchange since 1998; my real strength lies in problem-solving. You'll make my day if you can give me a problem that nobody can figure out!
I specialize in PHP development, usually in LAMP environments, but my programming experience extends to other web-based languages (ASP, Miva, ColdFusion, Perl, etc...) and client-side languages (the .NET suite, C#, Visual Basic 3.0 and up). The most common theme in all my applications is interconnectivity, so I'm well-versed in network-level subject matter, as well. I understand sockets, DNS, and different network protocols like SMTP, and know how to implement and debug them. I've also been gaining a bit of experience with different version control systems over the years, namely Visual SourceSafe, Subversion, and Git.
I've also done my fair share of network administration on both Windows domains/servers and Linux/BSD servers (although I haven't used any flavor of BSD since 2001). The Windows territory connects me to topics like Active Directory, SQL Server, Exchange, DHCP, and Terminal Services, as well as the regular can-you-fix-my-computer problem topics (PE booting, hardware, etc). Linux server admin experience gives me some background in shell scripting/Bash, BIND, MySQL setup and tuning (server settings and also in-server optimization, like proper indexing and query optimization), SSH, OpenSSL, compiling issues, cron jobs, and basic Linux sysadmin tasks.
I do contract work, but I only have limited times during the evenings, so I usually only handle 1 or 2 concurrent projects. If you want to reach me for contract work, please send an email to jon at sitecreative dot com. My typical hourly rate is $150 per hour. This is negotiable based on the length of the contract.
