OBJECTIVE

A programming job working alone or as a member of a team


EXPERIENCE

2009 - Present              Self Employed                   Richardson, TX
FREELANCE CONSULTANT

  I write Perl scripts and modules under contract.  PostScript-Report
  was released to CPAN; my other work was not suitable for CPAN release.

2004 - 2009	                 TRX                        Dallas, TX
ETL PROGRAMMER
  I wrote and maintained Perl scripts to Extract, Transform, and Load
  credit card and travel data from various formats into DB2 and MySQL
  databases.  I also helped design and implement TRX's Generic File
  Processor framework to simplify this task.

1999 - 2004	   Travel Technologies Group / TRX	    Dallas, TX
PROGRAMMER FOR CORRE AND ENCORRE

  I helped maintain CoRRe and EnCoRRe/CORREX using Borland C++ for
  Windows.  This involved using multiple GDS reservation systems and
  Oracle databases.

  In my spare time, I rewrote our email delivery system.  The existing
  system was a combination of C++ and a homebrewed scripting language,
  was slow and difficult to maintain, and had numerous bugs.  My
  version, written in Perl, is much faster, more reliable, and is
  still in use.

1993 - 1999	         Schoolhouse Software               Denton, TX
PROGRAMMER FOR THE PC GRADEBOOK

  I wrote the DOS version of The PC GradeBook in C++ using Borland's
  Turbo Vision text-based windowing framework.  I later ported it to
  Windows 95 using MFC, Visual C++, and the Standard Template Library.

1989 - 1993	         Schoolhouse Software	            Denton, TX
APPLE II PROGRAMMER FOR GRADEBOOK IV

  I completely rewrote a menu-driven gradebook from Applesoft BASIC in
  6502 assembly language, and gave it a spreadsheet-style interface.
  I was the sole programmer and the primary designer, with input from
  the company owner.


EDUCATION

1989 - 1995	     Youngstown State University        Youngstown, OH
BACHELOR OF SCIENCE, SUMMA CUM LAUDE
Major: Computer Science   Minors: Physics and mathematics   GPA: 4.0


AWARDS

2004 - TRX XCELLER AWARD (2ND QUARTER OF 2004)
  One award is given each quarter per 100 employees to recognize
  top-performing employees nominated by their coworkers.  I received
  it for my work on CORREX.

1993 - YSU UNDERGRADUATE AWARD IN COMPUTER SCIENCE
  One award is given each year for outstanding academic achievement in
  the study of computer science.

1992 - MEMBERSHIP IN PHI KAPPA PHI
  Phi Kappa Phi was founded in 1900 to recognize and encourage
  superior scholarship in all academic disciplines.

1989 - NATIONAL MERIT FINALIST
  YSU gave me an Outstanding Scholar's Award scholarship.


OPEN SOURCE WORK

My open source programs are available at my website, www.cjmweb.net.

PERL
  In 2010, I gave a talk about PostScript-Report at YAPC::NA.

  In 1998, I rewrote the Win32 IPC modules (part of libwin32) to
  remove unnecessary code, fix an egregious bug, and remove some
  limitations in the API.

  In 1997, my Getopt::Mixed, AppleII::Disk, MSDOS::Attrib,
  MSDOS::Descript, and Tie::CPHash modules were chosen to be part of
  O'Reilly's Perl Resource Kit.

  A complete list of my Perl modules is available at
    http://search.cpan.org/~cjm/

GNU EMACS

  I rewrote the internals of the Emacs perform-replace function to
  allow the replacement to be a Lisp expression.  (Someone else has
  provided a better UI to this feature by using \, in the replacement
  string to indicate a Lisp expression.)

  Decipher.el, a tool I wrote in Emacs Lisp for solving cryptogram
  puzzles, became part of the GNU Emacs distribution from the Free
  Software Foundation in 1996.

C++

  VBinDiff (Visual Binary Diff) is a tool for interactively comparing
  files at the byte level.  I originally wrote it in 1996 for OS/2.  I
  ported it to Windows and later added support for Linux (and other
  POSIX systems.)

  GUEmap was a program I wrote to learn Win32 GUI programming.  It's a
  program for mapping interactive fiction games.  I sold it as
  shareware for several years, then released it as open source in
  2007.

  Fast File Validator is a tool for verifying files against a checksum
  file and for creating checksum files. It supports both CRC32 and
  MD5.  (I'm using checksum in the generic sense. Technically, neither
  CRC32 nor MD5 is really a checksum.)  I wrote the Windows version in
  2000, and added Linux support in 2005.
