EXPERIENCE

2010.5-present VeriSign, Inc. Sterling, VA

Performance Engineer (Contract), VeriSign Naming Service

Responsibilities:

As Performance Test Specialist, perform VeriSign naming

service product load test execution and analysis, maintain

valid test environment.

As Test Automation Specialist, maintain and enhance test

automation tools.

Achievements:

Load tested and monitored servers running on VMWare.

Provisioned maximum capacity for VMWare hosts and guests.

Significantly reduced cost for physical servers while

maintaining performance test environment's reliability and

capability.

Enhanced production load monitoring and analysis with

automatic cron executed log file parsing and data

persistence. Presented volume and performance trend in both

table and charts. Provided instant view on production load

pattern. Significantly reduced data analyzing and test

planning time. Allowed quickly adapt to production load

pattern. Application was implemented in Java, GWT, Spring

Framework.

Reduced manual test effort with cron executed Perl and Java

application to automatically execute test, analyze result and

produce Excel chart report.

2009.11-2010.5 Convergys Corporation Reston, VA

Senior Testing Analyst, Intelligent Notification Product

Testing

Responsibilities:

As Test Automation Specialist, design and develop test

automation tools aimed to reduce test preparation, execution

and result verification time.

As Lead Test Analyst, participate in all aspects in system

test cycle:

Analyze product and functional requirements; plan test scope,

goals and objectives; prepare and document test cases;

Set up and maintain test environment, administer test

servers;

Perform installation verification;

Execute test cases and monitor test progress;

Use JIRA to raise, track and follow through bugs with

development team till resolution.

Coach and assist junior team members.

Achievements:

Designed and developed Media Server Simulator in Java that

polls jobs from Advanced Notification Gateway and returns

simulated response. The tool enabled phone-dialing functional

and load testing without using actual phone lines, eliminated

telecom cost and chance of calling real customers by error.

Designed and developed Call List Generator tool in Perl that

creates notification job input file containing dummy phone

numbers to user specified Countries and customizable

application data. The tool reduced test data preparation time

from hours to seconds. A call list detail report is also

generated along with the list that summarizes each category

of generated phone numbers and simplified test result

verification, which would otherwise involve manual counting.

Designed and developed PBX Simulator in JSP/VXML that can

simulate different PBX menu systems. Eliminated the need and

associated cost of setting up real PBX systems to execute PBX

extension-dialing functional test cases.

Evaluated web service testing tools; designed and developed

soapUI data-driven test suite for Web Services test

automation.

Evaluated web service load test tools; designed and developed

JMeter test suite to allow dynamic load change using external

Perl script.

Authored user guide for all above test tools and suites for

training purposes.

2009.8-2009.11 L-3 Communications Arlington, VA

Senior Testing Engineer, US-VISIT

As part of US-VISIT testing team, responsible for test

automation and manual test.

2003.3-2009.8 Convergys Corporation Reston, VA

Senior Testing Analyst, SpeechPort System Testing

Responsibilities:

As Test Automation team lead, design, develop and maintain

system test automation suites.

As Empirix product specialist, coach test automation team

members to maintain Hammer regression test database. Train

other test team members to use automation tools and

regression suites. Train development and application testing

teams on Hammer automation tool. Coordinate hammer resource

usage between teams.

Manage performance test environment and assist development

team to define load test goals, prepare test data/scenario

and execute load tests. Design, develop and maintain

performance test tools and scripts. Analyze and interpret

test results.

As senior member of the test team, responsible for all

aspects of system test cycle in components of SpeechPort

platform: Telephony Server (TDM and VoIP), Speech Gateway,

Speechport Application Framework, OA&M Framework, network

security, Cisco Content Switch, Cisco Call Services, Cisco

Audium Studio, Avaya Communication Manager and SIP Enablement

Server, Tomcat server, Resin server, Apache server, BEA

WebLogic server, Sonic MQ, VMWare virtualization and more.

Achievements:

Designed and developed data-driven Hammer regression test

automation framework. Automated end-to-end verification and

reporting including call session identification, voice

recognition, call log filtering and error detection. Over

1,800 test cases were automated. Human effort and errors

involved in regression test was significantly reduced.

Created a Web based system test portal to manage release

information, test environment information. Integrated with

Hammer test automation to monitor Hammer regression test

execution in real-time. Also used to review test steps, and

maintain test execution result. The portal became standard

tool for automated regression test in the organization.

Created SpeechPort Business Intelligence Portal web interface

regression test suites using Rational Robot. Automated 100%

of the test cases.

Developed Perl scripts to parse and extract data points from

load test log files and generate Excel reports and graphs on

response time and JVM GC statistics. The tool reduced time

required to analyze load test results from hours to seconds,

and helped development team to derive optimal JVM heap sizing

and system tuning parameters for production environment.

Played a leading role in jumpstarting the testing of

Intervoice Interactive Composer. Obtained in-depth knowledge

of Intervoice products by self-learning and trained team

members on Intervoice Media Server, CCXML/SCXML and QFTest

tool (a test automation tool for eclipse-based UI).

Eliminated expensive on-site training costs.

SCO;

Quickly became productive and played leading role in

developing Administration, Document Management, Issue

Management, Risk Management, and Progress Reporting modules.

Introduced systematic testing methodology to project team:

writing formal test case document and based on requirements

and use cases; planning-ahead test execution instead of ad

hoc unit tests by developers. Improved team efficiency in

identifying, tracking and resolving defects and improved

software product quality;

Followed full SDLC and developed Use Case document, database

ERwin model, UML model and user manual.

Learned to administrate SQL Server Database and became fully
