Sr. System, Systems Integration, and Test Engineer (Satellite, WCDMA Network 3G, Legacy and WCDMA Communication)

•         Test author for the Mobile User Objective System (MUOS) WCDMA and Legacy communications. This to include End-to-End (E2E) communications between Satellite, network, waveform, payloads, and UE radio users. Responsibilities include plan/procedure development, execution, and disposition. 

•         Test case development and execution for call processing between Satellite and UEs that included UE Registrations and call Origination/Termination. (I.e., Instant Messaging, P2P (Point-to-Point), Group, P2N (Point-to-Net), Handoff, G.729/MELPe voice, webpage and video downloads.)

•         Proficient at testing and integration of various WCDMA transports (Burst, Stream, and Flow services) via Layer 3 (IPv4) and Layer 4 (TCP and UDP).

•         Log software defects using ClearQuest and SharePoint bug tracking tools. Work closely with software developers to analyze the defects, track them to resolution, retest, and closure.

•         Authored discrepancy reports and performed integration/regression testing to verify/validate incorporated fixes.

•         Planned and implemented test solutions for system components. (I.e., Waveform, UHF-LES, Ka-LES, ETI, and RAN network.)

•         Analyzed system requirements, plans, test procedures, and test cases for P2P and Group tests. (I.e., collect data, analyze, and prepare reports from captured test results.) This to include software and hardware verification (system integration, UAT, and regression testing.)

•         Coordinate test activities between internal and external team members to seek best technical solutions, implement test automation, and analyze test results.

•         Resolved technical concerns relating to test implementation, setup, and calibration efforts.

•         Responsible for creating, editing, and executing XML, Perl and Python-based test solutions.

•         Collected and analyzed in/output artifacts. (I.e., RBS and RNC trace files, DoDump, and UE logs.)

•         Reviewed and validated all requirements or Pass/Fail criteria.

•         Individual contributor and (as part of multi-disciplinary team) effectively solved complex technical issues.

Nexius Wireless Inc.

IMS/Push-To-Talk Integration and System Verification Engineer

•          Developed test plans, test procedure, and test cases for IMS/Push-To-Talk, and PoC features based on OMA specifications, 3GPP Standards, MRS.

•          Analyzed call processing, SIP messages, SIP call control, Media Handling protocol included Register, Adhoc call, Adhoc group call, pre-arrange group call, Talk burst message, ...

•          Hand on and in depth know-how of IMS architecture, SIP protocol, HTTP, SIP, DNS, LDAP, Diameter, Streaming Protocols, RTP, RTCP, XCAP/XML, and TCP/UDP/IP.

•          Debugged, analyzed, captured, and generated software problem reports when test case failures in Gi link, network, IP phone.

•          Knowledge UMTS wireless infrastructure protocols in core, data, and networking architecture.

•          Utilized testing tool DebugMux, Ethereal, and TSP.

04/1998 - 01/2006

Motorola, Inc. South Plainfield, New Jersey

Systems Integration and Test Engineer (CDMA and GSM/GPRS/EDGE/UMTS)

•      Developed test plan, test procedures, test cases for new phone features and feature interact based on Synergy's documentation, Marketing Requirement Specification, and customer requirement.

•      Executed test cases within the PTT GSM/GPRS/EDGE phone, understanding test applications and methodologies.

•      Wrote scripts for automated test suits for regression, stress test, and documentation, update, and post test results by using Test Expert or Test Central tools.

•      Tested KPI (Key Performance Indicators) to measure Quality of Service of wireless voice and data services and end-to-end applications and analyze the test results.

•      Executed phone features and sanity test plan include automated and manual testing.

•      Reviewed functional specs, identified test cases and scenarios, developed traceability matrixes, plan and prepare test data, executed test plans, analyzed and reported on defects, and coordinated with development teams upon test failures.

•      Verified bug fixes, and worked with cross-functional teams to fix problems.

•      Used debug and analyze tools to capture logs, panic and power down data, analyzed test failures, and generated software problem reports (using DDTS tool).

•      Diagnose RTP and SIP protocol stack traces using Wireshark and RTA tool.

•      Configures the systems; provided failure analysis and corrected failure related test data (Datalog, panic code,…)

•      Validated test cases base on CDG Stage 2 Interoperability by changing and implying all call processing (e.g.: Mobile Orig./Term SMS, POTS - Mobile to Land Party Call, Handoff (Soft/Hard), Registration, etc.).

•      Verified test scripts to identify problem from the phone or Racal's scripts, analyze the failed test, and generate problems reports.

•      Interfaced with various development organizations to drive resolution of software problems discovered during testing.
