GE Energy (March '08 - January '12):Industrializes hot gas path (buckets, nozzles and shrouds) repairs on H (steam-cooled) technology at Toshiba GE-Turbine Services (TGTS) in Yokohama, Japan. Generated millions in revenues at TGTS by implementing H repairs. Developing new repair technologies with Global Research Center and Repair Development Center for new product introduction (NPI) turbines (7FA.04, 7FA.05 & 9F Growth). Drove implementation of lean methodology throughout NPI processes.GE Aviation (October '05 - March '08):Led cross-functional global team to realize contractual service agreement savings, worth millions of dollars, on cold airfoils hardware, which doubled the expected target in one year. Orchestrated technical data and supported business development group to pursue a majority ownership of Airfoil Technologies International in Singapore, an undisputed leader in repair of low and high-pressure compressor (HPC) airfoils, to improve GE Aviation balance sheet. Drove development of solid-state welding technology to repair complex 3D aerodynamic geometry of HPC airfoils across multiple engineering departments within GE Aviation. Developed and implemented repair solutions on fan and high pressure compressor (HPC) for CFM56, CF6, GE90, CF34, GEnx, GP7200 and other engines. Supported global network of repair shops (OEM, revenue share partners and third-party) by issuing and publishing cold airfoils repair documents annually in multiple engine manuals. In addition, hardware owner for repair on GE90 high pressure turbines (HPT) blades. Transitioned GE90-94B HPT blades from Glades to GEASO and captured millions of US dollars in savings.

GE Aviation:Designed, analyzed and certified all 9 new stages of 3D aerodynamic HPC blades on CFM56 Tech Insertion and CF34-10 engines, which increased compressor efficiency by 0.7 point to save airliners in fuel and maintenance cost. Retrofited and validated 9 new stages of 3D aerodynamic HPC vanes on F110-GE-129 Service Life Extension Program engines to improve performance and fuel efficiency. Reduced direct labor productivity by $1M at HPC vane sector manufacturing facility by using laser process, which elevated production yield by 85% in 1 year. Redesigned CFM56 high-pressure turbine shroud from N5 material to a low-rhenium material and captured material cost savings of $310K annually. Gained manufacturing processes and utilized Gemba Kaizen methodology to reduce cost while maintained design intents. As hardware owner, responsible for all design changes and support field experiences.
