Echostar’s Local Storage Disk Video Recorder (LSDVR) is a DVR appliance receiving ATSC broadcasts. The system is comprised of a 5 tuner set top box and one or more dual element antennas.The RFTest Diversity System is a Windows 7 laptop with an embedded Debian Linux VM that’s used to characterize and place ATSC antennas as well as collecting & reporting LSDVR tuner/demod statistics for developing diversity algorithms. An Apache/FCGI application server hosts a Javascript/Ajax/CSS webapp driving an embedded C LSDVR library via custom Tcl packages, all running in the Linux VM. Given the need for realtime data collection, Tcl was also chosen for the RESTful app server. • Architect, lead (3 member team) and platform engineer for the LSDVR RFTest Development System.• Designed and implemented I/O routines in C for FTDI FT2232H USB/I2C bridge providing command and status access to the LSDVR’s tuner, demodulator and RF sections. The whole LSDVR C library was then wrapped in its own Tcl package making it available to the FCGI app server.• Designed and implemented a custom Tcl package with C style structs & enums making the LSDVR readily scriptable for diversity algorithm development and status logging. The package includes a bi-directional JSON/dict facility with support for arbitrary JSON arrays.• Designed and implemented a test framework that allowed developers to easily script diversity tests utilizing arbitrary tuner/station/antenna bindings in Tcl.• Designed and implemented a job control system for managing diversity test execution from the webapp. A task manager thread shares the exclusive-use LSDVR with the browser/FCGI client thread. The job manager thread manages a scheduling FIFO populated by the webapp. Both immediate and time-delayed jobs are supported. Specialized single-step jobs allow techs to spatially characterize reception by moving an antenna through a grid with a smart phone app triggering task manager data capture for each cell.

Cailech Systems is a small engineering services firm providing hardware, software and technical engineering services for consumer electronics and enterprise clients.

• Designed and implemented several DAO modules for the Content Engineering group based on Spring 3.x’s JDBC Template and the 1.6 JDK. The deliverable included a JUnit test suite along with JMeter/JUnit Sampler integration tests.• Designed and implemented a continuous-integration (CI) build-system for the Content Engineering group. The prior system used the Ant-based artifacts generated by the NetBeans IDE as the basis for a build system managed by a build-engineering group. It was replaced by converting to a Maven/Jenkins/SVN system that supported either NetBeans or Eclipse IDE’s. SVN checkins triggered Jenkins builds that checked out and built the codebase, ran unit (JUnit) and integration (JMeter/JUnit Sampler/JUnit) tests and if successful, deployed the applications to their respective servers. Build artifacts, both development and release, were archived to an Archiva Maven repository. As a result, the build-engineering group was no longer needed.• Designed and implemented a continuous-inspection facility for the Content Engineering group. A variation of the CI system, the Maven Sonar plugin was used to orchestrate Cobetura, Findbugs, Checkstyle and PMD plugins. Specialized nightly builds evaluated the applications for optimality, cyclomatic complexity, code-coverage and style.• Designed and implemented a comprehensive Jenkins/Maven/SVN provisioning system for Sezmi’s networks and their environments. Sezmi’s TV service was comprised of two network configurations. One had 14 server types, the other 8. The servers were a mix of LAMP, Tomcat, Apache and JBoss platforms. Packages included: MySQL, Liquibase, JBoss, Tomcat, CAS, LDAP, SSL (with both wildcard and SAN certificates), PHP, Kohana HMVC framework, Memcached, Java 1.6 JDK, Spring, c3p0, JAXB, SLF4J, JAX-WS, Jersey/JAX-RS, Apache, mod_ssl, mod_jk and mod_proxy.

• Architect of TellAPal’s second-generation platform. The original JSP/Servlet design was replaced with a Restlet/Spring/Hibernate/MySQL backend and either Javascript/Ajax/CSS, GWT/GWT Restlet Engine or PHP/Smarty front-ends. Though extensible, the RESTful service API’s primarily utilize HTML, XML and JSON Representations. • Designed and implemented a reward-fulfillment service utilizing a custom Tomcat/Restlet bridge, Spring-Framework managed Hibernate DAO’s and a MySQL database. A Restlet Resource provided a RESTful API service for processor-based (e.g. Paypal) plugins. The initial plugin set included WSDL/SOAP and CSV file implementations. • Designed and implemented a Maven-based development environment with Eclipse/SVN/Ant integration supported by local Archiva Maven repositories and custom installation/deployment utilities.

• Participated in the design and implementation of a new Application Server for Radix based on a Resource Orientated Architecture (ROA) using the Restlet framework.• Developed information model for geolocation database using IDEF1X ERD’s. Defined, normalized and tuned a MySQL physical implementation of the model using the InnoDB storage engine. Database access was handled via Spring framework enabled DAO’s providing transactions and database attribute constraints.• Implemented RESTful Resource Representations and their associated JDBC DAO’s • Redesigned and implemented an Ant-based build system for their Java server builds. The new system built both release and development configurations with integrated Checkstyle format checking and TestNG unit test integration. The build system checked, built, tested and deployed the primary Application server.

• Designed and implemented a per-resource, declarative, thread-scheduling-policy facility based on OpenPFC’s POSIX threads. OpenPFC was a C++ device abstraction layer used by Pioneer’s Blu-ray players. Its threading model supported timeslicing and a single fixed round-robin realtime priority. Now, each resource’s entry in the plugin loadmap optionally defines a list of scheduling-policies (i.e. scope, type, priority).• Replaced the JVM’s 2-value fixed-priority threading with separate scheduling policies for each of Java’s 10 priorities via the new PFC thread facility• Designed and implemented a PFC MediaController facility to arbitrate user stop requests with PFC end-of-media events. The singleton PFC EventServiceRoutines (ESRs) also ensure the MediaController‘s Listener list remains coherent across PFC start/stop transitions. Components included Java classes, C++ classes, and JNI routines.• Redesigned and implemented JMF’s MediaPlayer/MediaController state machine and event generator. Added a state-transition facility for managed controllers and their players that was independent of the JMF transition-event facility shared with clients. Controller state was phase-locked with the transition-event state so that users of the Controller state API “see” the same state as clients of the event system.Pioneer’s Profile1 Blu-ray players supported 4 InteractiveAudio (IA) resources that can be graphed into mono or stereo configurations as clients see fit. Those 4 resources were transparently shared among an arbitrary number of JMF InteractiveAudio MediaControllers.• Redesigned and refactored JMF’s InteractiveAudio controller facility. The new facility managed a pool of IA resources to dynamically generate stereo or mono resource graphs while preventing rewiring whenever possible.

• Architect and lead engineer on YourIT’s Adaptive DAO Store (ADS) project. • Designed and implemented ADS using a variety of Open Source components, particularly the Spring Framework, Apache’s WSIF web-service framework, Apache Axis, Tomcat and the MySQL DBMS.• Architect, business analyst and middleware engineer for YourIT’s ADS Security System application. Based on ADS, ADS Security offered an n-tier digital-video security-system for a variety of businesses. ADS Security provided camera scheduling, system configuration and layout, camera resource management and event-storage services using a simple browser interface.• Modeled business tier using transformation graphs• Developed ERD and DDL for MySQL database

• Architect and lead engineer on the Fathom Service Bus (FSB) project, an SOA middleware platform that provided a Web Service facility for FCM’s B2B and B2C applications. Designed around Open Source components, FSB presented a simple Producer, Consumer, Data-Controller bus-environment that relieves application modules (applets or servlets) from network/transport and database issues. Producers manage DataSources using augmented Spring Framework Application Contexts and custom Java Beans. FSB was successfully deployed to host Fathom’s Keyword Price Index (KPI) application.• Designed and implemented FSB• 1/2 of team that designed and implemented a data collection ETL facility (FDC) for collecting high volume “click” reports from search and tracking (e.g. DoubleClick) engines via Java and WSDL API’s, e-mail, and downloaded reports. FDC provided session-retry and recovery support while also functioning as both build system and data-report archive.

• Designed & implemented iMPP (iM Portable Player), a realtime, C++, multimedia-framework for PIM. iMPP managed audio/video content for WAN (live), LAN (jukebox via UPnP), and file streams. One multiplexed and 15 independent media pipelines were provided for network and codec plugins. Arbitrary data packets (with extensible metadata) were clocked through the pipelines without copying. Pipeline nodes (player, content source, decoder, renderer) ran in their own threads with iMPP scheduling their interactions in realtime while providing memory (packet and control structure), network, and content-parsing resources to plugin classes. Plugins ran in a simple, synchronous, node-environment, free of resource contention and event management. iMPP was ported to Linux, Nucleus, Win32, and WinCE. Plugins were done for both MPEG/MP3 & WMA/WMV.• Created multicast network modules for iMPP (SDP, RTP/RTSP). By successfully integrating LiveCaster’s live.com libraries into iMPP, a large number of audio and video codecs were reliably added, along with the multicast support.• Created pluggable Win32/WinCE network-plugin for iMPP. The plugin provided a “pluglet” framework that allowed external media players to run unmodified as iMPP network-content plugins. COM Pluglets were done (by others) for both the Format SDK and Windows Media Player.• Designed & implemented HTTP 1.1 server with configurable thread pools and pluggable protocol handlers for PIM’s networking module. The server parsed and scheduled client “jobs” based on HTTP protocol elements.

Half of the team that designed and implemented the middleware for iMonitoring’s distributed security system. Dedicated Java (2 SE) clients captured security-camera video and streamed it on demand to a DataCenter. Standard browsers were used to view, retrieve, and save client security-video via iMonitoring’s portal.• Developed key class-library to represent DataCenter sessions for both camera clients and iMonitoring’s website. While presenting video as simple Java byte-streams, the class hierarchy multiplexed video and metadata while transparently providing routing and server load balancing.
