PROFESSIONAL EXPERIENCE

Nortel, VoIP Development Jul 2008–Mar 2009

Senior Software Engineer Richardson, TX

• Reverse-engineered then enhanced an undocumented 7 KLOC system configuration and monitoring tool

written in Core Java and Swing for the purposes of adding network infrastructure-based firewall-rule

generating capabilities.

• Developed a set of technical documents detailing backup/restore and security hardening procedures on

the Nortel Ethernet Routing Switch (ERS 5000) for use in a Geographic Network Redundancy feature.

Nortel, Media Gateway Development Oct 2005–Jun 2008

Senior Software Engineer/Project Lead Richardson, TX

• Acted as the project lead for a team of nine software engineers developing a real-time embedded carrier-

grade Signaling Transport application for the purpose of allowing a wireless mobile phone provider to

transport its legacy SS7 network traffic over an IP-based network. Application designed using object-

oriented analysis and written in C++ for the VxWorks operating system.

• Project lead duties included leading document reviews and design discussions, ensuring all project

requirements were addressed, ensuring all hardware and test tool requirements were met, answering

protocol & component interaction questions, mentoring junior engineers, and working with team

members to track project milestones.

• In addition to project lead role, served as a developer writing 90% of the High Level Design document

along with the architect. Designed and implemented the Signaling Transport model (which made up 75%

of the application) into an existing 8 KLOC M3UA protocol stack. Designed and implemented the

configuration interface used by the system engineers to configure the application.

• Involvement with this project was throughout the entire software development cycle, from analyzing

functional requirements to field deployment and support.

Nortel, SGSN Development Jul 2002–Oct 2005

Software Engineer Richardson, TX

• Designed/implemented 2 KLOC worth of enhancements to a real-time embedded carrier-grade API for

communicating with a remote Home Location Registry in a wireless mobile phone network, as part of a

feature for calculating the location of a mobile handset, using object-oriented analysis and C++.

• Designed a cyclic redundancy check (CRC) API for detecting memory corruption out in the field, which

was usable in a real-time embedded system, and then integrated its use into 20 KLOC.

• Department lab coordinator; responsibilities included configuration and maintenance of Nortel Passport

15K-based GPRS and UMTS SGSNs, including ARP & IP network configuration, for use in automated

traffic testing of Nortel data software loads.

Nortel, Automated Tools Development Jun 1998–Jul 2002

Software Engineer Richardson, TX

• Using object-oriented analysis and C++, designed/implemented/enhanced a series of 5 KLOC client-

server applications and user APIs which implemented various wireless network communication protocol

stacks for the purpose of assisting in the verification of Nortel’s various voice and data software products.

• Provided 1st and 2nd-tier day- and night-time customer phone support for internal product verification

teams. Tasks involved troubleshooting hardware such as single-board computers, HP 9000s, and Dell

network servers, as well as analyzing and debugging client-server automated test applications running on

Red Hat Linux, VxWorks, and HP Unix.

• Developed and instructed several classes for end-users detailing the use of automated test platform, and

for the members of the team regarding the design and implementation for the platform.

• Mentored both junior engineers and recent college graduates.
