What I'm looking for

I seek engineering roles focused on thermal management, simulation or data-center operations where I can apply CFD and operations experience, work in collaborative teams, and grow technically.

I am a mechanical engineer with hands-on experience in data center operations, thermal systems, and simulation-driven product development. I have supported HVAC and power system operations at a large EPC firm and led multiple academic projects using ANSYS, SolidWorks, and data analysis tools to improve thermal performance and safety.

My projects include large-scale Li-ion battery thermal simulations, fatigue analysis using ANSYS and machine learning, wind energy investment modelling with Power BI, and automation-focused mechanical design. I combine practical operations exposure with simulation, data analysis, and leadership experience to deliver reliable, optimized engineering solutions.
