EMPLOYMENT HISTORY

POWER LINE SYSTEMS, INC October 2008 - Present

Senior Software Engineer

PLS provides software for transmission lines design, including tower and

pole design, and line stringing and sag-tension calculations. Focused so

far on published thermal rating techniques, LiDAR data processing for

feature extraction, and material cost tracking. Programmed in C++, using

Microsoft Visual Studio, SourceSafe, Perforce, OO.

TELVENT MINER & MINER, INC November 2006 - September 2008

Software Engineer

Developed GIS software for mapping, analysis, and management of facilities

for the utilities industry (electric, gas, water). Focused on optimization

algorithms for underground and overhead electrical lines. Programmed in C#,

C++, VB6, COM, and ESRI's ArcObjects. Used Visual Studio, SourceSafe, NUnit

for unit tests, OO, Oracle, SQL Server.

THE SPITFIRE GROUP, INC October 2005 - July 2006

Technical Specialist

Oracle, SQL Server, including a client's SharePoint intranet portal, and

Spitfire's company website and client portal.

MERILAB, INC November 2004 - September 2005

Independent Software Consultant, then full-time Software Engineer

Developed a Windows application in VB.NET that interfaced with displacement

sensors of an automobile alignment system via PLC, collected tire profile

data from the sensors, displayed 3-D profiles of the data, filtered and

modeled the data, and calculated tire misalignment.

INDEPENDENT SOFTWARE CONSULTANT

- BITSOFT SYSTEMS, INC (consultancy company) August 2003 - October

2006

Performed, off and on, project management tasks for BITSOFT and

developed software for clients of BITSOFT on a subcontractor basis.

Specifically:

* BITSOFT's client AGILENT TECHNOLOGIES, INC: Added features in C++

to AGILENT's software for automatic testing of printed circuit

boards, and project managed a team in India that implemented

outsourced tasks.

* BITSOFT's client SNOWLIONBOOKS, INC: Developed a Web application in

C# and ASP.NET that maintained an Oracle database of books and

consumed web services of other Internet vendors.

- NEXTSIGMA, INC August 2004 - March 2005

Developed software tools in VB.NET for statistical analysis of data,

charting, and reporting, while taking training classes and obtained 6-

sigma black-belt and master-black-belt certificates from sister

company SIGMAPRO, INC.

HP/AGILENT TECHNOLOGIES, INC. 1996 - 2003

R&D Software Engineer, Electrical Manufacturing Test Division

Designed, patented, and implemented algorithms for automatic testing of

analog printed-circuit boards and for resolving PCB deflection problems

that occurred during test. Key accomplishments include:

* Researched and implemented in C++ on UNIX and Windows original

mathematical modeling and optimization techniques, as well as plate-

deflection theories, resulting in a total of 12 patents.

* Wrote prototype software with 3-D graphics to visualize/validate

solutions, using C++ and MATLAB. Built prototype hardware to debug and

test the software using simple resistors, capacitors, inductors and

relays on breadboards.

* Wrote patents and design documentation. Helped the documentation team and

developed computer-based training software to aid in training.

EDUCATION

UNIVERSITY OF WISCONSIN-MADISON

Post-Doctoral Fellow, Mechanical Engineering Department 1993 - 1994

Biomechanics - Researched techniques for the biomechanical analysis of

the human musculoskeletal structure. Developed software for modeling

sports and medical activities interactively and analyzing muscle forces

and joint reactions.

Robotics - Published book on Robot Motion Planning with John Wiley &

Sons, Inc.

PhD Degree, Mechanical Engineering with minor in Computer Science & Math

1986 - 1993

Planning Collision-Free Paths - Investigated, developed and implemented

efficient algorithms for planning collision-free paths for objects moving

between obstacles in 3-D space, with focus on the computational

efficiency, optimization of the paths, and conformity to practical

constraints on the velocities and accelerations.

MS Degree, Mechanical Engineering 1984-1986

Robotic Hands - Analyzed the geometry of the workspace of robotic

manipulators and hands. Developed and implemented an algorithm for

optimum placement of fingers on a palm to maximize the workspace.

CERTIFICATES

Six-Sigma Black-Belt & Master Black-Belt certificates, SIGMAPRO, INC

2005

Took 6-sigma black-belt and master-black-belt training classes while

developing for a sister company software tools for statistical analysis

of data, charting, and reporting.
