The final prototype for my university capstone project required a high strength to weight ratio that previous iterations failed to provide. By redesigning the frame geometry using SolidWorks and validating the stress distribution through ANSYS, I achieved a 22 percent increase in structural rigidity while simultaneously reducing the component mass by 150 grams. This successful proof of concept demonstrated that precise computational analysis directly informs physical performance. I bring this rigorous, data driven approach to the Product Development Engineer role at Nexus Precision Manufacturing to solve complex mechanical challenges.

My academic and project experience centers on applying design for manufacturability principles to real world problems. During a summer placement, I implemented GD and T standards on four subassemblies, which decreased assembly time by 18 percent and eliminated clearance errors. Utilizing COMSOL, I conducted thermal analysis on composite housings to optimize heat dissipation, improving cooling efficiency by 12 percent under peak load conditions. Additionally, I managed a rapid iteration cycle for a 3D printed mechanical linkage, reducing production turnaround from ten days to four days by refining the assembly tolerances in AutoCAD.
