PROFESSIONAL EXPERIENCE:

Confidential, Boulder, CO

Software Engineer

Responsibilities:

• Developed a Qt GUI front end in C++ for a harness testing script (Ruby based)
• Developed a set of Python scripts with a Qt GUI C++ front end to assist in transferring issue and change record archives from Rational Synergy to JIRA.
• The Python scripts process the Synergy database dump, map Synergy to JIRA fields, reconstruct attachment files and their meta-data, and create a .CSV file for import into JIRA. The Qt GUI C++ front end controls the Python scripts and launches an HTTP file server to facilitate uploading of the attachment files during the JIRA import.

Confidential, Arvada, CO

Software Design Engineer

Responsibilities:

• Developed LabVIEW GUI application for a peristaltic pump test fixture.
