RELATED EXPERIENCE
CISTERA NETWORKS PLANO, TX
SYSTEM ENGINEER
JUNE 2008- MAY 2009
Came up to speed in short period of time and became important contributor.
Enhanced existing and developed new features for Cistera's Convergence Server, which adds functionality to Cisco Call Manager environment and VoIP equipment; Created, executed and documented test cases and scenarios.
Troubleshooted customer issues of both cross-layer and application nature that included: installation and configuration of Cistera's Convergence Server (CCS) VOIP application on a Linux, Java, Ingres and Cisco Call Manager environment, replicating customer case in in-house test lab, finding the cause of the problem; Steps to follow included: solving the problem or finding the workaround, explaining and documenting the problem and solution (TCP/IP, VoIP, SIP, SQL, XML, Java, Ingres, Asterisk).
ORTIVA WIRELESS LA JOLLA, CA
R&D ENGINEER, CTO OFFICE
SEPT 2006-MAY 2008
Manage feasibility studies, design, and development of in-house test beds and procedures for real world network emulation.
Reported directly to CTO of the company.
Execute detailed theoretical and experimental work covering broad range of wireless networks (CDMA 1xEvDO, 1xRTT, WiMax...)
Established RF and IP network profiles for simulation and emulation purposes for Agilent 8960, Spirent SR5500, Apposite Technologies Linktropy, and Nistnet.
Conduct research on the effect of RF and IP parameters including multi-user presence, AWGN, SNR, power variation, and error rate on the QoS and QoE.
Plan, execute and analyze network emulator tests to measure QoS parameters such as VQM, MOS, and other objective and subjective quality measures for rich media streaming.
Assess IP/UDP/RTP protocol stack as well as IP/TCP/RTP and the impact of protocol layering and IP layer packet fragmentation on multimedia streaming.
Utilize MPEG4 and H264 encoding standards and open source encoders including ffmpeg and x264 in improving video frame quality and error resilience while maintaining video encoding efficiency optimal.
Coordinate with other companies and conduct product evaluation in purchasing required network and video products/services (Agilent, Anite Nemo, SwissQual, Symmetricom...).
Utilize expertise in excel and Matlab in examining data and log files.
Performed extensive work on emulators and test beds: Agilent E6651A WiMax/WiBro tester, Agilent 8960 CDMA/ HSDPA tester as well as onsite testing within tier one carrier WiMax labs and deployment sites.
Plan and perform effective demonstrations to investors and potential customers, provide appropriate explanation on the set up of the environment and the user experience on different levels; for engineer, present detailed information and for sales-oriented visitor utilize abstract point of view; manage equipment and execute presentation.
Key Accomplishments:
Proactively improved operation of the company by recommending and generating numerous methodologies to product development
Developed values for RF and IP parameters that describe WiMax network (packet loss, bit error rate, min/max bandwidth, frequency of variation) and contributed to the development of in-house test lab for emulation of different networks (linktropy).
