I work on the database of all genetic information. I'm creating a virtual file system and virtual database that can run on several platforms. Handling large amounts of submitted data (up to hundreds of terabytes per submission) we can load numerous file formats into a standard database format that can be used for genetic alignments.We also create a toolkit for scientists anywhere to work with the biotechnical data on their own systems with our tools or those they write themselves to use our data formats.State of the art object oriented techniques primarily in C to provide solid portable interfaces for libraries.I created the new archival format to hold database tables in a portable format that can be used without unpacking the archive and reduces the operating resources used by limiting the number of file handles to one per archive..I also created an encryption format for files that like the archive format and in conjunction with that format allows keeping personal genetic information secure while still allowing access to the data on the fly without decrypting the file to disk.I created a new government owned clean AES block cipher that is compiled in various forms to allow optimal performance based on the features of the specific processor running the software. This includes the new AES-NI instruction set from Intel.

Continuing engineering for an SNMP proxy agent running on Pentium II processors in a cPCI chassis running Tornado/VxWorks. This is the same product I worked on for Spike Broadband Systems a year earlier; my work the previous year earned me a call back for two contract positions worked semi-concurrently. Designer and developer of an SNMP proxy agent for radios running on a hub modem's processor for a wireless broadband system. This is the product to replace the SNMP proxy agent mentioned Continuing above. Developed the software that runs on both the radios and the proxy agent for communications across an RS-485. Designed the private MIB for this proxy agent using ASN.1. Used the NucleOS kernel for the proxy agent running on a Power PC/QUICC processor and for the radio the 68HC16. Left when all projects completed.

Senior development engineer and network administrator. Team lead in engineering. Project engineer designing and developing software in C for a switched as opposed to routed IP. Project lead on a port to Intel IXP1200 of this software in C and microcode. This port used embedded Blue Cat Linux Project lead on a remote access to Linux routers running this switched IP for demonstration purposes. Used Java, C and shell scripts to allow TKL/SNMP based demonstration program to run on a laptop running Linux to reach out through a firewall and back in through another firewall at Signafor's offices providing real-time access to statistical information about the interfaces on the routers. Left when company closed its doors.

Project leader, and principal developer for an SNMP proxy agent for hub radios for wireless broadband networking. This proxy agent was built using Tornado/VxWorks as the base O/S, Rapid Control for the user interfaces and Envoy for the SNMP agent. This system provided an FTP server and HTTP server as well as the SNMP agent. Primarily developed in C and HTML with JavaScript. Used HP OpenView particularly NNM and Unix scripts in ksh and Perl running on Sun Sparc Solaris platforms for configuration and testing of the embedded proxy agent. Installed Linux on a laptop PC and wrote scripts to program PCMCIA/Compact Flash modules for booting of the proxy agent. Used Rational ClearCase and ClearQuest management tools running on Unix and Windows 2000. Used MS Office 2000 tools for documentation. Took requirements from customers/product management through analysis through the whole product life cycle for subsequent releases. The team for the spike radio proxy agent consisted of my self and a mid-level engineer who handled a portion of the JavaScript and html coding under my direction. I handled all areas including code handling generation of web pages on the fly and much of the JavaScript and HTML. My team finished releases on or ahead of time with minimal expenditures; this allowed more time for the Q/A phase. Designed look and feel for web page user interface that was so well received it was incorporated into other Java based NMS products for Spike. Led the NMS team on configuration management and defect tracking. Participated in QA at all levels for this product allowing the QA department more time to focus on other products that need more attention than the relatively defect free radio proxy agent.

Performed system and network administration of a TCP/IP, X.25, and Frame Relay network for the Veterans Administration. I and two other engineers came into a failing contract and turned it around to the complete satisfaction of the end client. My role was primarily the Unix administration and C programming with other work in FORTRAN. Did program enhancement and maintenance using Oracle's Pro-C and Pro-FORTRAN extensions to both DEC C and FORTRAN and Sun C and FORTRAN. Single handedly took over all work on billing system. Took requirements from product management and accounting departments within SAIC to develop new versions of system for billing of VA and paying of network service sub-contractor - Sprint. Optimized code and SQL access to Oracle to reduce ungainly program runtimes in days down to mere minutes for billing programs. Took customer requests through all stages up to deployment on the production systems. Performed systems administration duties for Sun Solaris, Alpha Tru64 Unix and VAX/VMS systems. As project lead, supervised other engineers in the successful port in one weekend of the whole system including scripts, cron utilities and batch files and dozens of programs from VAX/VMS to Alpha/Tru64 Unix. All of the difficult sections were reserved for me based on my skill level. Performed other coding in C/C++, FORTRAN and scripting languages on all platforms. Project ended when Sprint was awarded the subsequent follow contract without SAIC's participation. Left when SAIC contract with the VA expired after several extensions

Used a C/BSD Unix development system to write device drivers for a net attached NFS storage system. The platform was a PC running a proprietary system and RAID drives and numerous network interfaces.

Embedded DSP and CISC programming for AT&T/Lucent Technologies DACS II and DACS II ISX cross connect switches. Technical lead, designer and implementer of WE 1611 DSP code to handle sub-rate multiplexing and multipoint junctions. My architecture and design for an object-oriented architecture allowed the DSP card to far exceed expectations. A previous version handled 55 channels with no error correction or junctions while the version my team created handled 64 channels with error correction and the multipoint junctions. Also worked on the CISC master MC68000 family processor for the TG-193 DSP card. The success of this project led directly to another project awarded to GRC by Lucent. In this project I served as technical and project lead on a major release of code for the DACS II that added Hybrid DS3 capabilities where T1 and E1 channels could be constituent parts of the data stream. Coding, design, management, code control and system administration duties. My team accomplished in 9 months the equivalent of what it took Lucent's staff two years to complete. Work in C/C++ and assembly. Development platform was Windows NT for DSP work and Sun Solaris for Motorola 68k family work. Helped administer the Solaris systems at GRCI, then helped train the hired Unix and Windows administrators. Left when contracts with AT&T/Lucent completed.

Integrated and updated software for a highway sign reflectance application. The platform was a PC mounted in a van with a strobe, reflectometer and range finder in a through the roof periscope. Although I was hired only as a one day engineer expected to fix a simple "assembly language defect" I assessed the actual state of the project. My role changed from a hired specialist to rescuer of a floundering project when another engineer could not interface C to the hardware. Used Borland C and Assembly on DOS. Left when project canceled
