At Walton Hi-tech Industries Ltd, I lead R&D for indoor and outdoor HVAC modules, including structural design and feasibility work for 19.2 TR VRF systems. I also research materials such as Aluzinc, HDGS, and polymers, and assess cooling performance against ISO standards.
Earlier, at Charm Ltd., I designed CAD fabrication drawings and pipeline layouts for water treatment systems. As an Undergraduate Research Assistant at KUET, I used CFD and CAD to study vehicle spoiler placement; the research was published and presented at ICMIEE 2014.
