NetApp, or memory, and migrations. Perform activities for both Linux and Windows Server
Vms. Consulted with Senior staff about performance or advanced VM issues.

• Maintained in house development server.
Project Lead.
• Designed and implemented a VOIP project, selecting hardware and software required. Wrote
JAVA code to interface data entered via the telephone keypad with other software products
that Crescent offers. Java was also used to provide call data recovery features via an
intermediate database. Other technologies include SIP, T1 lines, Asterisk (Soft PBX), and Red
Hat (Fedora Linux). The project went into production after 1 week of beta testing, advanced
features, reliability, and ease of use.

▪ Applications did not have to be recompiled.
▪ Users could specify severity of the error, and who should be alerted. .
• Coded an application for conversion of reports to PDF, and present them on the web.

114 ), print any single page, cancel, spool on hold ( to allow for check paper or other paper
changes ), move jobs to a new target device.

saved the banner and print job to another area, so that jobs could be reprinted days or weeks
later.
