Intel SoC SDK

Intel's CE4100 Sodaville, CE4200 Groveland, and dual-core Berryville were system-on-a-chip media platforms targeted at set-top boxes, VCRs, and smart TVs. The SDK was used by partners such as Logitech Revue with Google TV and Boxee Box.

I started on the team as an OpenGL driver developer and moved to SDK lead, initially focused on packaging and release but then taking technical leadership for the SDK 2.0 initiative. I managed around 20 SDK releases per year. I also led bug scrubs, performed initial triage of issues, and interfaced with customers. For the SDK 2.0 project, we built a new CI infrastructure. I co-architected the design, led the planning, and supervised the development team during implementation.

Native Netty Driver for Java

Lightfleet makes a high-speed DMA-based optical interconnect and targets the high-frequency trading industry. The drivers and library were in C, but prospective enterprise customers used high-level languages like Java. To more effectively reach this market, the company wanted to make its products usable with the Java ecosystem. As the C library and SDK owner, I was given this project.

I identified the Netty project as suitable for our purposes. I developed a JNI wrapper for our C library and built a Netty datagram transport on the native layer. A multi-threaded Java client/server demo achieved five million packets per second, fully half the speed of optimized C.

Wireshark 802.16 Protocol Analyzer

Developed an 802.16 client MAC simulator to validate a server project, including protocol analysis at the bit level. I then led a team to further develop the code into an open-source Wireshark (formerly Ethereal) plugin. The code was contributed to the Wireshark project and can be found in the plugins/epan/wimax directory of the project website.

Shockwave 3D

Shockwave 3D is a web media platform. I worked in a team to develop game technologies for the platform in C++ and led the scheduling and physics subsystem. Shockwave 3D shipped to more than 40 million desktops.
