Manufacturing Industry 
Manager of Manufacturing Engineering – responsible for the engineering and maintenance departments.  Applied the “RPM method”; resulting in an achievement awards on behalf of a team effort for “Reduce machine downtime from 20% to 2%”.  Increased production line by 30% through new in-house designed equipment. Scrap rate approached zero.  A division that went from “red” to “black”.  
Power Industry ( coal and gas fired ) 
Senior Plant Engineer…Design, supervised installation and start-up of new control logic to increase reliability and maintainability.  Control system projects included:Turbine controls…(2)  450 MW steam turbine and (2)  300 MW combustion turbineBrine Plant…Coal Handling… Air system… Sludge conditioning…Flyash… Precipitator… SCR CEMS (Continuous Emission Monitoring System)… Scrubber… Coal Handling 
 Bulk Material Handling Equipment..
(stacker reclaimers , barge unloading / loading, conveyor belt systems, vibrating feeder, etc.) 
Senior Field Engineer / Construrction Manager– start-up of customer’s asset in all industries (International travel).  . Responsible for subcontractors and construction personnel on multimillion dollar construction site during installation.  Knowledge of mechanical, electrical and controls engineering skills requiring only one engineer on site .Crew size varied from 4 to 55, both union and non-union personnel. 
Coal Industry
(Strip mining equipment…Draglines, shovels, wheel excavators, overburden drills, etc.)  
Mechanical Engineer - participated in the necessary modifications to coal surface mining equipment.  Developed graphic presentation of equipment modification with emphasis on interchangeability of parts and installation procedures.
