Objective

Seeking an opportunity to work in a challenging environment where I can leverage my skills, experience and capabilities in technologies such as C/C++, Perl and IP networking to contribute effectively to the success of an organization.

Experience

10/2014 – 10/2015: Spirent Communications, Matawan, NJ

Senior Software Engineer

As member of customer support for Spirent’s InTouch Customer and Network Analytics Solution, worked with team to troubleshoot customer issues and monitor their systems for potential problems.

Contributed to the existing base of JUnit tests for software modules in InTouch.

Developed JMeter scripts for performance testing of the web interface for InTouch.

Technologies: Java, JUnit, JMeter, Agile Development, Linux, Windows

9/2012 – 1/2014: Dialogic, Parsippany, NJ

Software Engineer

As member of Dialogic’s Host Media Platform (HMP) development team, provided support for the HMP API Infrastructure and testing tools, eg: 1) Diagnosed and corrected details related to improperly formed media container files. 2) Fixed bug in packetization of H.264 NAL units into RTP packets.

Technologies: C/C++, Perl, H.264, RTP (RFC3984, Linux, Windows

4/2008 – 7/2012: Dialogic Media Labs, Eatontown, NJ

Senior Member Technical Staff

Contributed to the successful launch of a world-class video quality assessment solution. One area of personal contribution focused on integrating our software quality measurement “agent” into a variety of mobile devices.

Integrated quality assessment software into recent versions of the Android OS: 1) Froyo running on Nexus One phone, 2) Gingerbread running on Nexus One and Nexus S phones and 3) CyanogenMod Gingerbread running on Viewsonic gTablet, Motorola Droid X, HTC Incredible, Samsung Captivate and Samsung Fascinate phones.

Integrated our quality measurement software into the FFmpeg H.264 decoder, allowing our product to work effectively with FFplay and VLC client software.

Supported the addition of features, testing and delivery of evaluation systems to customers as DML Video Quality Measurement (VQM) products developed.

Contributed to the efforts on the creation, presentation, and maintenance of customer demonstrations.

Created comprehensive and self-contained demonstrations for use with potential customers. These demos were premiered at the Mobile World Congress exhibition in Barcelona. This show is Dialogic’s most important external event, and these demos were the showcase of the Dialogic exhibit space.

Creation of these demos required a broad range of skills and experiences, including:

Modification of Darwin Streaming server to simulate packet loss by dropping specified frames from a bitstream.

Integration of content ID so that the demonstration could dynamically display a real-time description of the content being shown.

Definition of overall system architecture, as the earliest demonstrations showed how video quality measurements could be captured at an end device and delivered to a central host for further analysis. This required 1) Integration with the Android OS (Cupcake) for loading to Android Developer Phones, 2) Modification of JM H.264 encoder to support specification of a Qp value per frame allowing creation of bitstreams that enable mimicking a bad QoE session, 3) Modification of the Darwin RTSP server to support data collection, and 4) Development of QoE agent/aggregator and aggregator/reporter communications protocols.

Tuning quality parameters to create an effective demonstration of enhanced ‘rate control’ features, highlighting Dialogic technology.

6/2004 – 4/2008: Thomson Corporate Research, Princeton, NJ

Consultant/Senior Member Technical Staff

In newly formed group to add AVC Professional Profile support to internal H.264 Encoder and Decoder SDKs, added support for High 10 and High 4:2:2 profiles to Decoder SDK.

As team member/core team manager for H.264 Decoder SDK, provided technical support for internal business units and added the following features: 1) Slice-parallel multi-thread support, 2) Annex A profile and level conformance checking, 3) Annex C HRD conformance checking, 4) Parsing of VUI and HRD parameters and a number of SEI messages and 5) Integrated concealment methods for dropped disposable B pictures.

Added several tools to modified version of the reference model H.264 encoder: 1) Constant bitrate control, 2) Separate horizontal and vertical motion estimation search range selection, 3) Limit use of B Stored frames as reference to sub-gop in pyramid coding and 4) Support for interlaced modes when using Thomson’s proprietary Reduced Resolution Update extension to H.264.

As member of NIST VeDSL team, produced reference bitstreams for use by partners, Sarnoff, Alcatel and SBC (now AT&T), and worked with the partners in end-to-end testing for delivery of the bitstreams from server to Set-Top-Box. Also integrated concealment methods into network video player.

11/2002 – 10/2003: Lemur Networks, Eatontown, NJ

Video Architect/Software Developer

Built proof-of-concept prototype for enhancing Lemur’s i-Fabric™ self-service interface to enable VOD services. This involved developing two web-based applications: 1) Movie database browser/selector allowing 2) Set-Top-Box VOD interface simulator to access pre-selected movies.

Contributed to the GUI development for Lemur’s i-Fabric™ product line.
