Portrait of Siddarth Rajkumar

About Me

I'm a mechanical engineering student passionate about product design, CAD, prototyping, and simulation. I enjoy solving engineering problems through iterative design and developing practical solutions from concept to prototype.

My experience includes biomedical device development, mechanism design, finite element analysis, and additive manufacturing.
