Highlights
|
I have a long history of performing on challenging projects. Working alone or on a team. I pride myself on solving hard problems, making things fit (e.g. small memory footprint), making things fast (a lot of experience with optimization), and making things right.
I pride myself on programming in a focused and disciplined fashion. I try to get the job done fast, but insist on doing it right.

Embedded graphics
TCP/IP, EtherNet/IP, PROFINET
Experience from large systems down to small devices, requirements analysis through system test
Years of experience helping with hardware design and doing intial bring-up/integration of hardware.
Recent work:
Developed RTOS for fido processor
-- threading
-- mutexes
-- semaphores
-- message queues
-- memory pools
Ported commercial embedded TCP/IP stack to said RTOS
Ported commercial PROFINET stack to processor/RTOS. Included development of custom Ethernet MAC firmware (yes, it is a programmed MAC) to filter PROFINET real-time traffic to a high priority hardware queue separate from other Ethernet traffic (also provides high priority transmit queue).
Developed (with others) low-level libraries to take advantage of fido processor on-board peripherals, hardware threading, etc. |
| Additional Skills: |
Currently developing I2C library/drivers. Specifically for serial EEPROM and 3-port Ethernet switch. |

Work Terms

• Payment Method:
I operate through the Guru.com SafePay Escrow approach.
• Communication:
Preferred method is e-mail. The frequency depends on the size/complexity of the project. Email status reports will be sent at least twice a week, more often if necessary. Email regarding development issues may come more frequently. On complex projects I find that a phone call every other week or every week can be helpful.
Specifics should be decided upon when negotiating a project.
• General Availability:
To be clear, I have a day job. Therefore the best time to contact me is in the evening. However, if necessary, a time can be set up during the work day or early in the morning.
