PROFESSIONAL EXPERIENCE

Nokia (2011 – Present)

Engineering Manager Systems Verifications Performance Test.

• Manager of RF Performance System Test Group Delivering 4G LTE with Voice Over LTE to the KDDI customer in Japan. Stringent Requirement for voice and data performance testing and KPI’s were successfully completed to meet the System Level performance for this technology. Product deliveries include KDDI Dual Technology, CDMA/LTE/VOLTE Base Stations to be deployed throughout Japan.

• Test Architect for KDDI Japan 2.1 GHZ LTE/CDMA Project. Managed global team of test engineers, creating global system test strategy for functional and system performance testing. Lab allocation, capital and engineering test resources managed to successfully assure the product quality expectation for launch in Japan. This extremely rapid Program was delivered 2 weeks ahead of schedule on top of a 50 % planned reduction in Program cycle time.

• LED RF Performance Test group in testing SW Release Programs. The Complex RF Performance testing encompassed critical LTE features, Voice over LTE, Carrier Aggregation, DRX and Voice quality. Performance targets of maximum data throughput, low latency and call reliably were exceeded. Focus was on continuous SW improvement.

• Ran Daily meeting to address complex issue affecting data/voice call performance with High Level Systems Engineers teams, Development and RF testing. Reported results and status in weekly Operational and status meeting.

• Executed interoperability testing with QCOM new chipset and Prototype UE. This assured feature performance expectations prior to commercial deployment.

• Validated customer Performance parameters proposed for their commercial system via a real Over the Air lab in Finland.

Motorola Inc. Networks (2001 – 2011)

Engineering Manager, CDMA Systems Division, Systems Integration and Test

• Manager of CDMA/EVDO System Performance Test Group delivering wireless digital systems infrastructure to major operators worldwide. Product deliveries include KDDI Dual Technology LTE/CDMA 2000 1X Voice/Data, and EVDO Rev A. Consistently met all Project M Gate quality levels to bring products into commercial markets. Product deliveries were met while managing cost budget reductions moving performance test to low cost centers internationally.

• System Performance Test lead for New QCOM Qualcomm CSM8700 to support 1X advanced and CSM 6850 chipset 1xEV-DO “Rev B Capable” Modem. The new modems were deployed in Motorola’s primary Universal Base Station Product.

• Feature Manager for EVDO Rev A System Performance Regression Testing. Supervised cross functional test teams encompassing RF Performance test, Stability, Operability and availability testing.

• Managed Test resource for front end planning and execution for multiple Product Releases. Oversaw test strategy development, approach and coverage scope.

• Achieved quality target for pass rate, defect find and system performance parity for the release.

• Manager of Applied Systems Engineering (ASE) group. Managed Radio System lab and RF test function which consistently provided a high level of performance validation for CDMA system release. Key programs consist of EVDO- Rev. A, 3G–1X Voice/Data, Packet BTS, and major architectural additions to the Radio Access Network.

•Key accomplishments of the ASE group included:

•Achieved RF System Performance Test targets while identifying a 20 % increase in defects found and reducing time to resolution.

•Increased productivity 20 % via test automation achieved consistently for 5 years.

•Created 5 Innovation and Patent disclosures exceeding the annual team goal.

• Team Leader for transitioning ASE EVDO Testing to Motorola India (MIPL).

•Developed Training Program for MIPL

•Identified capital for new lab and RF bench test equipment.

•Oversaw present test execution EVDO at ASE –MIPL.
