Confidential, East Haupauge, NY

Linux System Engineer

Responsibilities:

• As a Linux Kernel Developer for two different defense oriented equipment companies I modified and debugged device drivers for the 2.4 and 2.6 Linux Kernels on Intel and PPC microprocessor-based embedded systems. Activities included debugging existing drivers, migrating device drivers from the 2.4 kernel to the 2.6 kernel, and updating low level interface libraries.
• All development was done using C/C++ and some assembly language on x86 and Power PC platforms.
• Device interfaces I supported included serial ports, PCI bus, ISA EISA bus, and memory mapped I /O register devices.
• Supported Mil-Std 403B type Computer boards and avionic type applications in supporting the Suse Linux kernel on a couple of different platforms (x86 and Power PC).
• Device Drivers were completely documented and released to a code revision systems.

Responsibilities:

• I provided low level test routines for a proprietary embedded system.
• Interfaces included PCI-E bus, USB packets, and memory mapped I/O registers.
• I also worked on single and multiple thread test routines for use in pre-production design tests for proprietary interface boards.
• All work was done using the Kiel embedded C development system on Power PC platform.
• Linux Kernel Device Driver Developer for a commercial equipment oriented company,
• I provided low level device drivers routines for a proprietary embedded system.
• Features included memory mapped I/ O registers in PCI address space, queuing of messages for driver to driver communication, and kernel user space data transfer routines.
• All work was done using C/C++ and Linux 2.4 on Power PC platform.

Project Leader and C Developer

Responsibilities:

• Debugged field reported problems involving light intensity, analog cellular communications, and other device modifications for existing products.
• Performed design verification tests.
• Environment included heavily modified Linux kernel and multitasking Linux support of analog cell phones and overheard messaging systems.
• Additional features included a User Application and other diagnostic features.

Confidential, Springs, CO

Project Leader

Responsibilities:

• I managed the activities of two additional software engineers, participated in the selection of a new platform and recommended purchase of a new development system for a next generation PPC based embedded controller.
• Day to day activities included debugging field reported problems involving light intensity, analog cellular communications, and other device modifications for existing products.
• I also worked with interpreting customer specifications and performed design verification tests.
• Linux Firewall Supported a Red Hat Linux based network firewall system that protected the Colorado Department of Labor computer network.
• This included debugging startup scripts, monitoring attacks, and analyzing network usage by job applicants through the use of Dan's guardian and MySQL UNIX software.

Confidential, Colorado Springs, CO

System Test Engineer

Responsibilities:

• Designed and developed a series of multi-threaded POSIX compliant test a programs used to test specific hardware features of a new multiprocessor computer system during the system integration and DVT phase of development.
• All tests were written in gnu c with some assembly language routines, ran under both Solaris 2.6 and Red Hat Linux 7.0, and were maintained using CVS.
• All test failures were resolved by working with the appropriate hardware engineers and by adding debug features to the test programs such as serial port trigger signals, reordering of operations, and capturing logic samples.
• Other projects included the design and development of an image-processing program used to demonstrate system performance at an industry trade show. This program was written in Java 1. 4 and used the AWT library of image routines along with semaphores, multiple threads, and socket communication.
