Designed, specified and developed a system to allow for scalable, unattended software transfers to and from Ennovates Envoy NetBSD and FreeBSD based switches. Designed and implemented a recovery method for Envoy operational images after they have been determined to fail. Consulted heavily in the implementation of the controlling MIB.

My other responsibilities included general UNIX consulting and education, assisting in the design of debugging techniques for various difficult bugs, reviewing design documents. Consulted in efforts to improve the existing network management system and storage of configurations.

Consulted on and helped design the Envoy System Control Processor dual redundant operation. Designed an I2C device driver. Investigated the usage of FlashDisk technology for the Envoys mass storage. Researched the effects of power failure and reset on the FlashDisks. Implemented and tested a modification to the WD disk driver to protect FlashDisks from corruption due to power failure. Assisted in the investigation of alternative solutions to protecting FlashDisks from both reset and power failure.

Investigated and determined the cause of poor disk performance. Devised a set of changes to the standard NetBSD WD driver that improved FlashDisk read speed by a factor of 20 and write speed by a factor of 10.

TopLayer Networks, Inc.: Chameleon Systems, Inc. ARC Cores, Ltd.: May 1998 -- March 2000:

Instantiated various flavors of gnat, a gcc based ADA compiler from ACT. Built and maintained gnu c, c++, binary utilities, gnat and gdb for Solaris and x86 Linux as native tools. Built and maintained gnu c, c++, binary utilities, gnat and gdb as cross compilers hosted on Solaris and x86 Linux for Power PC and ARC targets. Ran and analyzed the Plum Hall c validation suite for the ARC Cores processor, including fixes to gas.

Worked in a team to implement a new, more complete, set of ARC machine dependent configuration files for gcc. Upgraded gnu c, c++, as and ld to correctly handle the new compiler features.

Xedia Corporation: January 1997 -- September 1998:

Upgraded compiler tools (gnu c, c++, binary utilities and gdb) for Xedia. Designed and implemented the primary and secondary bootstrap loaders for their PCI based Access Point family of routers, integrating c++ drivers from the main development team into the bootstrap code.

Helped with the functional hardware design of a T-3 PCI serial communication card. Designed and implemented the real time firmware for the card. The firmware implemented the driver interface, and asynchronously controlled the HDLC and Line control functions, managed four DMA controllers and monitored the status of four FIFOs to insure the proper operation of the card.

Peritus Software Services, Inc.: November 1996 -- January, 1997:

Was a senior member of a team maintaining all versions of Stratus FTX (Fault Tolerant uniX). Participated in the design of debugging methods on a per bug basis. Was the senior member of several sub-teams, each targeted at a specific bug.

Clam Associates, Inc.: September 1995-- July 1996:

Was the senior developer on a team to upgrade Clams AIX based geographic disk mirroring prototype to an IBM marketed product. My tasks included writing and reviewing functional requirement, design, and test plan specifications. Also reviewed the existing architecture of both the pseudo device driver and the Kernel RPC protocol layer. Designed and implemented mirror write consistency and asynchronous mirroring. Radically rearranged the device driver and re-implemented major sections as state machines in order to remove special case code and reduce testing.

Banyan Systems, Inc.: September 1993-August 1995:

Was part of a team put together to triage, debug and correct UNIX kernel, device driver and protocol bugs just prior to the release of Banyan VINES 6.0. After FCS of VINES 6.0, Was the first point of contact for support (for 6.0 and prior versions) and SQA (for 6.00(10), the first maintenance release) for communications and protocol issues.

Also consulted on possible extensions of the UNIX based VINES kernel, including kernel stack size, file system throughput and robustness and tape device throughput.

Implemented a partial BSD socket interface layer on Banyans VINES operating system (based on SVR3.2) over Banyans proprietary socket interface. This layer implemented the features required to inter-operate among Banyan's proprietary VINES Internet Protocol, TCPIP and UDP over SUN RPC. This was accomplished without kernel support for select(1) or poll(1).

Reviewed the technical specifications for both EISA and MicroChannel Busses for the purpose of designing and implementing a generic interrupt sharing mechanism. Implemented the design, making it multiprocessor safe, robust, and failsafe. Modified all device drivers (in excess of 70) for the VINES operating system to use the interrupt sharing mechanism. Modified the multiprocessor startup routine to use the mechanism for support of cross processor interrupts.

Modified third party C++ NDIS 3.0 device drivers so that, with the support of a kernel shim, they could be bound into the VINES kernel.

Reviewed Compaq technical documents for the purpose of writing functional and design specifications for a UNIX Wellness device driver. The device driver controlled two Compaq specific ASIC for diagnostics as well as logging both critical and correctable errors to nonvolatile ram. Fan operation, ECC memory correction, chassis temperature, redundant power supply, EISA bus utilization, cumulative operating time and other conditions were monitored.

Implemented the driver, making it multiprocessor safe and self-configuring since the supported platforms had differing feature sets. The driver was part of the VINES operating system and provided support for third party services to control a server via RPC.

Epoch Systems, Inc.: June 1991--August-1992:

Reviewed marketing and engineering requirements for a project to provide conversion of Epochs proprietary backup format, implemented in c++, to industry standard data streams. Wrote a Functional Specification and a Design Specification for the project.

Was one of three engineers who converted Epochs Hierarchical Storage Management System kernel support from SUNOS 4.1.3 to Silicon Graphics version of SVR4. The conversion included making all kernel components multiprocessor safe. My areas of concentration were device driver modification to support SCSI-2 magneto-optical drives implementation of a SCSI-2 media changer driver, re-implementation of Epochs logical volume file system and multiprocessor locking.

Other tasks: architecture review, multi-processor locking issues, debugging of C and C++ user applications.
