Product Integration Engineer (IPv6, Storage)
|
Nov 2008 - Current
|
Team lead for the verification of a suite of storage products to ensure IPv6 compliance. Designed, constructed and supported a multi-subnet, multi-service IPv6 infrastructure to verify SLAAC, DAD, NDP, DHCPv6, and DNSv6 interoperability. Constructed discrete test cells to verify full support of the RFCs that describe IPsec, IKE, DNS, DHCP and the core IPv6 functionality.
Team lead for the verification of an enterprise class virtual storage device. Helped establish NetBackup and Tivoli storage environments, designed test cases and test schedules, provided technical support and direction to team members as needed.
Implemented HPC clusters (Sun Grid Engine and TORQUE) that supported batch and parallel jobs for "continuous run" testing of storage devices using the Lustre parallel filesystem with the goal of characterizing performance in a HPC environment. Developed simple MPI and OpenMP applications for cluster verification and benchmarking of storage devices.
Developed a utility (the "Executioner") that provided continuous execution of Veritas NetBackup jobs in a multi-node, multi-library environment. The application kicks off simultaneous backup, restore and verify operations using different types of data on multiple media servers of varying operating systems.

Designed and developed Personal Data Security (PDS), a MVC open source application written in Java that supports encrypting personal data and provides secure key management. PDS provides a multi-window text editor using JFC/Swing, manages an unlimited number of keys and provides the ability to use different encryption algorithms and key strengths for each type of data. PDS has a very fast encryption engine capable of encrypting multi-gigabit files.
Designed and developed EZQmail (EZQ), an open source qmail distribution system that dramatically simplifies the installation of qmail and the qmail-dependent programs while preserving Dan Bernstein's Copyright. Using an intelligent and modular approach, EZQ downloads, patches, compiles, installs, integrates into the OS and configures several of DJB's programs into a fully functional qmail system based on netqmail-1.05. EZQmail can also be found on SourceForge.
Designed and developed http://etpenguin.com, a website that supports the open source community by delivering advertisement free technical content on Application Development, Unix System and Network Administration, Internet Protocols, Network Services, HPC and Storage Infrastructures. ET Penguin relies on CGIndex for content delivery.
Designed and developed CGIndex, an open source tool that integrates with Apache to deliver content dynamically from a static filesystem, allowing active content producers to focus on producing content instead of integrating content into a website.
Designed and developed TARbackup, an open source backup application that uses a modular method to backup dynamic filesystems using open source tools. TarBackup supports both Full and Incremental (changes since the beginning of the month) backups that are easily managed using the Vi editor.
Enhanced existing (1999-) web development on http://scubanavigator.com, a MySQL-based website written mostly using CGI.pm and executing within Apache Registry; a few components have been written as Apache modules (mod-Perl). This site for all things Scuba contains powerful search engines, RSS feeds, free banner ads, many ways for visitors to contribute as well as an extensive set of back-end management tools for content control and feedback.
Enhanced existing (1994-) efforts on http://brettlee.com, hosting open source software projects, providing access to a Subversion repository via ViewVC and incorporating CGIndex for the dynamic rendering of pages.
