## BIO JEFFREY M. OLHOEFT TECHNICAL EXPERIENCE February 1998 to June 2003 - Network Programmer in Network Engineering Group at Intermedia Communications (now Allegiance Telecommunications) * Developed a backend DNS data management system using Java and Oracle. * Developed Next Generation traffic monitoring system using perl, RRDTool, and Postgres. System included determining network configuration, data collection, and report generation. * Developed router temperature, cpu load, and memory utilization monitoring software. Developed software to track changes in network route paths. * Generated ad-hoc reports on network status. * Wrote software and web-pages to track network hardware inventory. Wrote software to query, daily, all the routers in the network for the router type and any cards present, and generate a set of webpages reporting the result. Wrote a SQL based inventory management system to extend the tracking to all equipment, not just the equipment that was powered on and network connected. * Wrote a parser for the SNMP Management Information Base to enable quick searches of the MIB for variables to use in network monitoring. * Developed graphical representations of the network and network traffic flow. Wrote software to automatically collect data from several locations and generate "sub-maps" of the network with the desired network status data. Designed the mapping algorithm and incorporated it into a C based Perl module. * Helped administer the Unix servers and workstations my department was responsible for, including development, installation, and maintenance of system utility programs. October 1989 To January 1998 - Electrical Engineer in Motor Technology Group at The Black and Decker Corporation * Designed Universal, Permanent Magnet, and Brushless DC motors for use in hand held power tools. Some designs were modifications of existing motors, while others were clean sheet designs starting with the design of a new lamination. Focus was principally on improving power without increasing size over existing motors. Motor life was also frequently optimized, mainly in issues of brush and commutator wear. Electromagnetic interference and motor cooling were also investigated. * Modelled motor characteristics, such as speed-torque performance, torque ripple, line harmonics, and commutation. Worked on thermal modeling. Attempted to model radio interference generation of brushed motors. Measured magnetization characteristics of a steel sample for use in Finite Element software. * Wound and assembled motors and tested them for speed-torque performance, commutation, and temperature rise. * Worked on an advanced development team to survey customers to determine end-user requirements for a new product. Designed a motor to meet the set of product specs created by the development team. * Managed TIPS, a program to facilitate the implementation of employee suggestions to improve products and processes. * Developed software to simulate motor performance * Developed an electrical/thermal simulation package for universal motors. Wrote software to generate and manage magnetic libraries in C++. Provided general programming support. * Developed magnetic analysis software. Wrote mesh generation and post-processing software in C++. Dealt with cross-platform issues. 6/87-8/87 (Full Time), 9/87-5/88, 9/88-6/89 (Part Time) Physics Department, Case Western Reserve University * Assisted in theoretical studies of electron mobility in semiconductors. Helped write FORTRAN programs on a DEC Pro-350 and Micro-Vax to calculate electron mobilities by an iterative solution to a difference equation. 5/88-8/88, Los Alamos National Laboratory * Utilized Electromagnetism, Quantum Mechanics, and Fourier Analysis to developed equations to predict the penetration of anti-protons into various materials. Wrote FORTRAN programs on a Cray-1 to calculate penetration distance. ## Area of Expertise Languages \---|\---|\---| Java Perl SQL C/C++ VISUAL BASIC FORTRAN Pascal Assembly Systems \---|\---|- Linux Solaris CGI/Apache
