GENERAL TELEPHONE AND ELECTRONICS, Downey/Redondo Beach, CA

Training Specialist 4 Years

Was approached while taking a 480 hour training course (related to electronic telephone switching systems), to join the training team as an instructor. Formal request was made before the course was completed. Went on to become an accomplished instructor for 840 hours of curriculum. Course content included: 24 bit architecture, assembly language, machine code, operating system software, memory allocation, data structures, real-time interrupts, I/O communication, job scheduling, emergency recovery software, subsystem communication flow, power distribution, memory systems, electro-mechanical network, and oscilloscope operation.

Determined that existing course content was inadequate to fully prepare students for job responsibilities. Enriched the courses by arranging hands-on field trips to live systems and writing error message simulators. Enhancements increased the course impact and interest, greatly increasing trainee on-the-job effectiveness.
