RECENT MAJOR PROJECTS

• Worked with a non-internet company to capture the paper work flow for a jobs outreach program into a web-enabled database application using mod_perl and Oracle. The application manages the interaction between community contacts, job candidates, and the program management with respect to publishing job positions, scheduling interviews, and following up on hired candidates.
   
• Designed and developed software infrastructure for a completely automated shared-server web hosting company with: automatic account provisioning, automatic configuration of Apache, E-mail, and DNS daemons, a web based end-user administration interface, web based e-mail interface, enhanced e-mail storing and forwarding system, and various other features. Packaged all this into a custom RedHat based Linux distribution for easy deployment onto and configuration management of production servers.
