Providing an OpenWRT/Lede based Linux distribution to support 5G hardware environment. Implemented and maintain software development infrastructure including OpenVPN access servers BitBucket git server, Mantis bug tracking and Jenkins build environment. Integrate and/or develop software in either kernel or userspace depending on the needs.

Lead engineer for bare metal firmware developed towards a deeply embedded ARM Cortex M0+. Firmware is ROM based and very code size constrained. Designed and wrote code to provide boot functionality, RAM based code patching, i2c protocol and command handling, and device level power management. Integrated USB-PD and Type-C code from an earlier project created by a separate team. Mix of C/ARM Assembly developed using Keil uVision ARM tools.

The Linux Core Product Development team is responsible for the upstream Linux kernel development all of Texas Instruments’ ARM processors: Sitara, OMAP and Keystone multi-core. It also has the responsibility to provide productized, tested kernels to business within TI. My specific responsibility within this team is managing the deliverables of the Audio/Display/Capture portions for the Linux kernel.

Responsible for managing thin client engineering team and software product. Software product is Debian based Linux distribution. Team provides applications support directly to customers and has a clear roadmap for development of the software product.Currently software product supports TI DM8148, with specific accelerator hardware repurposed for thin client/VDI applications like Citrix HDX SoC Receiver and Microsoft RDP/RemoteFX.Significant X11 graphics optimization work was needed to optimize the dataflows to achieve maximum fps within the Citrix and RDP sessions. Now looking at how SGX GPU can be leveraged to further boost performance.

Provide broadmarket support and development services for IMG SGX GPU's included in TI Davinci / OMAP3 / OMAP2 silicon products.Provided guidance on 2D/3D programming strategies to Davinci customers to best leverage the accelerators that were available. Created the idea for a C6x DSP based blitter library and helped define and test it https://gforge.ti.com/gf/project/bitblit/.In depth understanding of SGX drivers and performance optimization techniques for graphics applications. Worked to accelerate Qt on Davinci platforms using combination of SGX (OpenVG, OpenGL ES, PVR2D) and ARM/Neon acceleration techniques.

Software Engineer for the TI Streaming Media group, taking the Davinci product line in IPSTB and other Streaming digital media applications.Successful ported first 2.6 Linux kernel to TI's DM320 platform.Created many tradeshow demos showcasing TI silicon capabilities when being used for broadcast video applications.Provided bring-up software support for DM6446 and customer support for TI AV Media Engine API's - created an example player application that supported a variety of network protocols (http/upnp, rtp/rtsp, multicast UDP) that could exercise functionality of the AVME and showcase the capabilities of the DM6446 device when used with network video backend infrastructure. This example player was eventually used as the basis for a number of customers media players.Was heavily involved in the silicon definition of the follow on DM8168 device, providing input on many of the lessons learned from developing media software on the DM6446.Very familiar with the Linux kernel TCP/IP stack through looking at ways to optimize (in hardware) checksum offload and using zero copy techniques to minimize the amount of host CPU that is consumed in IP streaming applications when interacting with the IP stack.Involved with a number of silicon bring-up's and provided debugging support on a range of different integrated IP blocks such as the Ethernet MAC and display subsystems.

Developed set top box firmware and media playback software for custom designed IPSTB based on VxWorks (StrongARM + Sigma Designs EM8400 chipsets). Lead the effort to port from VxWorks to FreeBSD and Linux to reduce the software royalties for the box.

Acted as IT guy for startup company along with developing the SQL / Visual Basic / C++ prototypes and demos of what became the Cramer OSS suite of products for the telecommunications industry. Responsibilities in this job were Oracle DBA on Solaris, Windows PC administration and C++/MFC development on Windows.

Ca

Firmware developer for CORBA compliant distributed networking infrastructure. Direct responsibilities were creating VxWorks BSP for a PowerPC MPC8xx embedded processor and a custom designed board. Maintaining pieces of the CORBA stack (C code) and Clearcase administrator for the group.
