Facilitated communication between US stakeholders and Canadian engineering team.

Authored the bulk of requirements documentation driving a team of 5-10 engineers.

Was placed as Senior Systems Architect for the Canadian office after several months.

Traveled continuously between U.S. and Canadian test sites, collecting customer (internal and end user) feedback, and translating these into requirements documents and necessary bug fix lists.

Provided monthly presentations to upper management concerning current risks, customer feedback, necessary changes, and overall progress.

Promoted to team manager for the last year before returning to GSI (Assumption, IL). SENIOR ENGINEER / ENGINEERING MANAGER, THE GSI GROUP, Assumption, IL; 2005 – 2009 Acted as technical lead for the design and maintenance for all of portable and Topdry embedded controls, and was promoted to engineering manager after the successful completion of GSI’s Vision Dryer controls.

Designed hardware for GSI’s Vision line of grain conditioning equipment, both schematic and layout using Orcad tools.

Design and development of all embedded firmware for GSI’s Vision line of grain conditioning equipment, including the boot loader allowing update of all distributed nodes from the central user interface.
