Welcome to Gaffa Razak's Portfolio
As a Consultant and Technical Advisor for Turbo-Generators, I leverage over 20 years of hands-on experience and global certifications in generator maintenance, overhauling, repair, and rewinding to deliver high-quality service and strategic support for power plant projects worldwide.
I have worked extensively with OOEM machines from ALSTOM, John Brown, Toshiba, Siemens, Mitsubishi, NEI-Parsons, Ansaldo Energia, ABB Sae Sadelmi, and Brush—resolving complex issues and ensuring peak performance in both steam and gas turbine generators.
My journey began as a mechanical semi-skilled fitter and evolved into a certified field engineer role specializing in generator erection for WX/WY ALSTOM Turbo-Generators. Since then, I have led and supervised numerous turbo-generator projects across Southeast Asia and beyond, working with diverse technical teams and adapting quickly to challenging environments.
I am a proud member of IEEE (Institute of Electrical and Electronics Engineers), actively staying engaged with global engineering standards and best practices in electrical rotating machinery. My membership strengthens my technical credibility and ensures my work aligns with the most current advancements in generator technologies.
My mission is simple: to deliver reliable, efficient, and safe solutions that extend asset life and ensure power generation continuity—especially for aging fleets where experience matters most.
