Biography

University of Illinois Springfield Springfield - Computer Science

Software engineer programmer, enjoy developing embedded systems: experienced, reliable, adaptable. JGTEK Inc. contractor
Computer Software
John
Garvert
Springfield, Illinois Area
I am a proven contract software & system engineer programmer, specializing in real-time embedded systems, C, C++, Ada, assemblers and many more, repeatedly demonstrating responsibility & adaptability to each customer’s unique environment rapidly: target system & technology, computer languages, tool set and procedures (ISO 9000, SEI, 2167A). I frequently have been given additional responsibilities that I have assumed.

I have developed full life cycle systems on Linux & Windows platforms. I have used many languages, interpreters, operating systems, scripts, and software development tools including configuration management and IDEs.

I have significant laboratory experience integrating aircraft & torpedo target systems hardware, firmware & software, communicating through industry standards & proprietary legacy IO devices: serial & parallel buses, discrete/analog sensors, direct memory access, Ethernet TCP/IP & UDP and application protocols,

Software functional capabilities, some with safety critical requirements: navigation, mission planning, embedded databases, autopilot guidance & control, fuel systems, engine control, communications, data recording, sonar DSP, interfaces to several navigation devices (from inertial to GPS) plus targeting with EO/IR, radar, fire control systems.

Several years ago, I returned to Central Illinois for family reasons. During that time, I founded JGTEK Inc., my independent contractor business, earned two additional degrees while providing family farm management and geriatric care.

As I have done throughout my career, I am continually enhancing my education to keep my technical acumen sharp. I have significantly expanded my technical horizons: aviation system, education instruction, surveyed new technologies (software, embedded LabVIEW, networking & IoT), and business & agriculture management. I have attended conference for Internet cyber security & defense and precision agriculture.
