Where Chemical, Mechanical & Electrical Engineering Converges to Power a Nation

For over five years I have worked at the intersection where fuel becomes electricity—a place where the heat of heavy oil, the spin of a turbine shaft, and the hum of a generator coil converge into the megawatts that power Bangladesh's homes, factories, and cities. My practice spans HFO-fired power plants, Wärtsilä marine engines, INNIO Jenbacher gas engines, and exhaust gas boilers. Every shift in the control room is an act of applied engineering.

"A megawatt is a responsibility. Engineering is not what you know — it is what you do with what you know."

Through this platform I share hard-won operational knowledge across chemical, mechanical, and electrical engineering. Whether you are an industry professional, an aspiring engineer, or a student curious about energy generation — this is your gateway to the plant floor. My weekly newsletter, Megawatt Insights, delivers exclusive industry updates and expert guidance directly to your inbox every week.
