Performed structural and thermal simulations using ANSYS and ABAQUS to analyse stresses, deformations, and heat distribution in mechanical components. Ensured accuracy through proper material definitions, meshing, and boundary conditions. Conducted CFD simulations in ANSYS Fluent to evaluate fluid flow, pressure drops, and thermal behaviour in various mechanical systems. Focused on improving performance and efficiency through flow path optimisation.

Jan 2022 - Present • 4 yrs 9 mos

Designed accurate, high-quality 3D models and detailed 2D drawings using SolidWorks for a wide range of mechanical parts, assemblies, and industrial components, with a strong focus on design intent, functionality, manufacturability, and real-world testing. Supported startups and small businesses in transforming product concepts into complete, prototype-ready designs, delivering print-ready files such as STEP, STL, and DWG with appropriate tolerances, fitment, and material considerations. Worked on diverse projects including gear systems, mechanical brackets, heat sinks, electronic enclosures, custom fixtures, and tooling, while providing design revisions and technical guidance throughout the development process.

Mechanical Engineering Intern

KAPCO • Parttime

Jul 2022 - Aug 2022 • 1 mo

Completed an in-depth internship at Pakistan’s largest combined-cycle power plant with a total generation capacity of 1,600 MW. Studied the working principles and operational procedures of gas turbines, steam turbines, HRSGs (Heat Recovery Steam Generators), and cooling towers. Observed multi-fuel operations, control room monitoring, and plant safety systems, gaining insights into energy production, equipment reliability, and system efficiency.
