About Hein Oo

Results-driven Professional Engineer with over a decade of experience designing, maintaining, and troubleshooting mechanical infrastructure in mission-critical environments — from nuclear generating stations to hyperscale data centers.I specialize in keeping the systems that can\'t fail running reliably: chiller plants, evaporative and DX cooling, water treatment and distribution, emergency diesel generators, fire suppression, and building automation systems. My career has taken me from the engine rooms of merchant vessels to the control rooms of nuclear power plants to the data halls of some of the world\'s largest computing facilities.What I bring to every role:• Deep technical expertise in mechanical system design, troubleshooting, and lifecycle management• A safety-first mindset shaped by years in nuclear-regulated environments• The ability to translate complex engineering problems into clear procedures and actionable solutions• Cross-functional leadership — bridging operations, maintenance, design, and construction teamsI\'m passionate about reliability engineering, continuous improvement, and building the infrastructure that powers the next generation of technology.
