• Developed control software for managing positional data streaming from a third party device, via a STM32 low voltage interface and the ARM embedded code including test to the FPGA Peta-Linux environments; all by using embedded software architecture and design patterns. • Task required defining and translating high-level requirements into software design and implementation.

• Productizing the software technology that has fueled the company’s past success. This involves the architecture, design and the key coding of a Yocto based build environment for a range of platforms (ARM, NXP, MIPS and X86) using the embedded Linux preemptable kernel, a proprietary rules engine and associated drivers, interpreters, and compilers; all designed for tight memory conditions and hard real time use. • The product goal is to speed up development reducing time and labor costs of new implementations and products for customers by having the same rules engine environment run all the way from the POST chip, to firmware, to FPGA ware, to micro executives, to drivers, up to large system middleware and up to full IoT networks. This product separates the process code from the hardware framework; making it easier and more efficient to do both and the customer product more transportable to new hardware in the future.

Earned a patent for designing and building a theater multiplex projection system based on a High Availability Linux serve using a fiber channel mirrored file system and applications. This system would accommodate the simultaneous delivery of feature length movies from the net and the decompression, decryption and delivery to up to 20 theaters at once. Architected the FPGA-based version for the next generation of movie encryption and decompression. Technology bought by Sony.Brought in originally to build the disk fail over driver for the High Availability Linux server that Vibren was partnering with Stratus Computer to create; which would become the basis of the theater multiplex projection system.

Prior to 1998, also Contractor to or worked for: Sky Computers, HP, among others.Additional Significant Skills & Accomplishments pre-1998* High speed network experience in iSCSI, Fiber Channel, SCSI-3, HIPPI and IPI-3 storage protocols.* Disk storage systems design including device driver creation and upgrading for several operating systems using the new high speed networks.* Experienced in the planning, management and integration of software implementations.* Electrical circuit skills include schematic tracing, test work, logic design, interfaces skills.* Deep experience in IoT closely networked embedded processor systems and associated firmware. • As software/system architect: Proficient at leading teams to successfully achieve a goal on time while ensuring that each team member is engaged as part of the solution.Example: Architected and built an embedded IoT system which reduced product shrinkage by over 90% on 12 legacy manufacturing lines using an IoT model of microprocessors and upper layers; included creating a network in an electrically noisy environment. • Created for IBM a cutting-edge 3D video micrometer measuring system using 4 custom designed processors built with ECL chips, using AMD bit slice devices. Architected the processors and interconnections, built the compiler, the Real Time executive and all the motion and video code.

• As software engineer: Exceptional problem-solving skills, notably a keen ability to comprehend the big picture while also contributing at the operational scale with practical and effective steps toward the solution, including coding.Example: Saved a client’s large avionics contract from default by creating a unique RT embedded system driver and developing a coding technique to compress the expected 30K+ lines of C code down to 3K lines and 6KB of data; this shaved over 6 months off the build time. Also defended the project before the FAA in the DoD-178 presentation for sign off on schedule. This became our company’s rules engine design of today. • Architect and builder of a embedded real-time product for standard Unix components including: "fair share" Unix kernel scheduler, upgraded interrupt and driver structures to allow hard real time (deterministic) use, rebuilt boot code and the INIT code so Unix SVR4.2 booted and ran disk-less from ROM for embedded use. Before there was Linux there was a Unix real-time environment.
