Responsibilities included: system architecture, roadmap definition, management of strategic relationships, prototype of new product concepts, early development of some key product features

Led several new platform initiatives: C2 Microsystems, VIXS, Zenverge, TI

Primary customer interface to key partners

STB Telemedia, San Jose, CA – Co-Founder/CTO 2008-2009

I co-founded STB to develop a suite of applications for the set top box, centered around a QT media application launcher and a media framework designed to quickly develop and distribute network media applications on C2 based platforms (with or without a local disk).

CEO was Marie Toulantis, ex-CFO of Barnes and Noble, ex-CEO of barnseandnoble.com

Core applications included:

o vPhone app: video phone application which supports multiple network discovery and access methods (including MDNS and SIP).

o Media Browser: a fully functional web browser, based on WebKit (the core of the Apple Safari browser). It includes the STB media plugin, a multi-codec media player designed to bring full screen, networked media streaming to web-based content. The most popular web pages work

(e.g. youtube, google video), but the best experience is with a web page designed for TV rendering (e.g. http://www.youtube.com/xl).

o Youtube browser app

o Twitter app

o Last FM internet radio app

o Flickr photo app

o Download manager

o System Management

o Various other streaming media apps (audio, video, pictures) with an emphasis on social networking.

STB had a strategic relationship with C2 and offered consulting services to C2 customers. C2 offers system hardware design services to STB customers.

STB had seed funding from angel investors, but has not been able to raise a large enough round of financing to get into production.

C2 Microsystems, San Jose, CA – VP Engineering 2004-2008

C2 was founded in San Jose. It is a fabless semiconductor company, based in San Jose, with offices in Beijing, China and Teipai, Taiwan.

I was the first software engineer there and quickly became VP of software and later VP of engineering.

In addition to managing I stayed technically active throughout my tenure there, implementing much of the kernel internals and early compiler/development tools myself.

I was also actively involved in the processor architecture and C++ media framework design and implementation.

I ported QT to C2 and developed a set of applications using the QT embedded window manager, targeting internet delivered media content.

TiVo Corporation, Al Viso, CA – System Software Engineer 1997-2004

I was with TiVo for its first 6+ years. I began by taking responsibility for the core OS (Linux 2.4) which was modified to implement TiVo hardware support, some scheduling extensions and a disk IO subsystem for embedded video devices.

I worked on the initial TiVo system (analog video encode/decode), the DirectTV system (decode only), the TiVo UK system, the TiVo combo system (DVD player + DVR).

I worked on the Linux OS, GCC cross development tools, the TiVo Media Object system for both the Series 1

(PowerPC based) and Series 2 (Mips based).

Auspex Corporation, San Jose, CA – Distributed Storage Systems Architect 1997-1997

I started a project within Auspex to design and implement a low cost, highly scalable distributed storage based on the Linux OS. The company ran into severe financial problems and my whole team was layed off after only a few months.

NEC Systems Labs, San Jose, CA – VP, Architect Golden Gate Operation 1995-1997

GGO was a joint development project led by NEC to produce a 64-bit Unix System V OS for enterprise applications on Mips based systems. Participants included Sony, NEC, Mips, Tandem, DDE, Concurrent Computers. NEC took the leadership role. I took a leave of absence from Tandem to direct this project. Tandem Computers, Austin, TX – Fault Tolerant Systems Architect 1991-1995

Education

Indiana University, Computer Science 1974-1978

I started as a music/math double major, but switched to computer science during my sophomore year. I had a strong interest in applying computers to music and worked with the music department on a set of CAI

(Computer Assisted Instruction) programs for teaching music and instructed graduate music education students in CAI Software Development. This ran on the Plato Tutor system and utilized a very early 4-voice synthesizer. I left school short a few credits from graduating, but completed them during summer school at the University of Louisville and while I was on staff at Purdue. I had problems transferring credits and never received my formal degree.
