Our Team


Greg Scallon

Chief Engineer

Founder and Chief Engineer of Commercial Computer Systems, brings over four decades of software research experience to our team.  He specializes in effective real-time distributed system designs based on performance modeling to improve system effectiveness. 

Greg has applied his extensive engineering skills to create the simpleXecutive Methodology which includes REAL Blueprints, REAL Language and SIMPLEX simulation design automation tool, which models a system's performance based on its defined structure and characteristics. These tools synthesize system level interactions between hardware, software and communication subsystem modules. The newly patented tools have successfully verified system design performance against complex distributed system effectiveness goals early in system development, i.e. prior to initiating coding.

Greg has acquired a broad experience base as Chief Computing System Architect for multiple successful large scale, real-time projects. This experience includes commercial avionics, manned Apollo Moon Mission, medical diagnostic and therapeutic systems, DoD weapon systems, and Star Wars experiments.  Optimized system level performance on complex real-time distributed systems is the hallmark of his designs.

Greg retired from Boeing as an Associate Technical Fellow after 30 years of successful aerospace experience specializing in complex real-time system design, performance modeling and evaluation, and basic research for a wide variety of large scale embedded real-time distributed systems.

His subsequent CCS career includes successfully solving many complex real-time medical and avionics system design development challenges.
