  • President, Fortuitous Technologies, Austin, TX Jan 2000 -> Current:

    Performance and Capacity Planning for corporate networks. Network documentation and revision. Extensive Linux kernel configuration and installation. Implement XFS, JFS, Ext3, and Reiser filesystems. DNS, NFS, NTP, OpenSSH, Httpd, Samba, and related software maintenance. Perl, Bash, and Csh scripting utilities for internal and external use. Configuration of thin clients and LTSP. Installation and configuration of Debian, Redhat, Gentoo, Centos, Suse, Knoppix, and other Linux distributions. Use of advanced package management utilities including APT, APT-RPM, DPKG, Emerge, and Up2date. Serviced clients with multiple printering environments, CUPS, and LPRng. Countinuous interfacing with clients, vendors, contractors.

  • Research Associate, Applied Research Labs, Austin, TX 1999:

    Developed C++ software in the Solaris/Unix environment. C development and debugging of legacy code, Qt GUI development. Training Documentation Development. Made extensive use of the Standard Template Library (STL) for designing data representation.

  • Senior Engineer, GDE Systems Inc., San Diego, California 1996-1999:

    Duties included administration of Solaris and SGI machines, implementation of automated ftp and CGI services, web servers, automated services, perl scripts, and general sh/csh shell scripting. Performed complete software installation and maintenance throughout all projects. Administered Perl on multiple NT platforms, and software for advanced source code mining.

    Implemented research to identify and classify agricultural products using imaging techniques that rely on spatial properties of satellite and aerial images. Designed and supervised research program for testing of spatial properties of satellite imagery.

    System Designer for Image Reduction and Characterization using wavelets, wavepackets, fractals, and similar technologies. These techniques are used in conjunction with several feature identification methods including K-Means, parametric classification, and neural networks. Conducted software installation and maintenance throughout project. The primary software tools for this work were Khoros and Matlab.

    Image Processing Algorithms Designer and integrator in development of multi-spectral image process tool for ground image decomposition and product quality control. C-Toolkit developer for the integration of custom image processing software into the ERDAS Imagine software environment.

    Software Installer and Administrator of Perl, Apache, and Fastrack servers. Created and maintained Perl routines for automated data acquisition via ftp, cron, and extensive Perl modules.

    Developer of C++ software for 3D applications in feature extraction. System Designer for data structures for use in virtual reality (VR) applications. Software Developer for fitting image data to preset building models. Performed hardware specification design for the VR testbed environment.

    Conducted software testing and design for radar cross-section analysis. Performed extensive testing and data simulation for same system using C++ in a Unix environment. Conducted database, GUI, C, and system development routing and logistics software. Applications interfaced with several databases including Sybase and Ingress.

  • Research Scientist, University of Valencia, Dept of Astrophysics 1995:

    Conducted numerical analysis in quark-neutron matter with applications in hydrodynamics, thermodynamics, and sub-atomic chemistry. Conducted algorithm development of neutron matter and numerical model verification. System Administrator for HP and Linux workstations.

  • Research Fellow and Scientist, The University of Wisconsin, 1990-1994:

    Applied numerical analysis to model dense neutron stars under U.S. Dept of Education Fellowship. This work sought to understand the phase transitions between matter that may happen inside neutron stars. Involved extensive numerical modeling of super-dense material using C and Fortran.

    Researched models of space-time with close timelike loops using maple, mathematica, analysis, and Unix.
