Working with the GNU/Linux stack since 2003 and freelancing since 2015. Many of my projects have been for embedded systems and have used the C or C++ languages. Below is a list of recent clients and employers, and of projects I completed for them.
I am always interested in discussing new projects; feel free to contact me to discuss yours. I have a particular interest in work that will be contributed to open source projects and will offer highly competitive rates thereon.
Gnarbox, the world’s first mobile solution for viewing, backing-up, editing, and sharing HD footage, needed a platform device driver to control a USB port mux based on the status of GPIO/interrupt lines. I authored this driver in addition to helping with various other low-level issues.
“… The mux switch and gpio config are out in the field with a few thousand users and still going strong, so well done…”

I have successfully contracted with Zodiac Inflight Innovations, a leading provider of in-flight entertainment solutions, on numerous projects.
Encrypted distribution of media content to seatback units.
“Our work with Rick involved low level communications between an RS-485 seat actuation system and our IFE System. Under an extremely tight schedule for one of our most important customers, Rick provided a software solution that met our customer’s needs with a high degree of quality. The requirements for this software were fluid and Rick was agile enough to update the design and implementation to meet the new requirements in a timely manner while communicating effect with stakeholders.”

I created a block device driver which intercepted
struct bio instances destined for a problematic storage device, performing necessary hardware resets while holding those instances in queue.
“… Reduced passenger initiated resets by 10%. …”

At SpaceX I helped with initial bringup of a PowerPC P2020 platform and maintenance of a PowerPC 8641D platform, including creation of device tree files and platform code changes. I made extensive changes to U-boot including introduction of new commands and adding new functionality to ethernet phy drivers.
