Welcome to my blog/online portfolio. I am Arulselvi Selvaraja, and I am a Mechanical Engineer (2018) with significant graduate coursework in Manufacturing, Control Systems, and Engineering Management. I have experience in project management, CAD, manufacturing, and control systems acquired through my co-ops and course projects. I enjoy problem-solving, making CAD models, and tinkering with electronics for fun. I also enjoy writing poetry, photography, and volunteering for organizations like the Lindy Center, Habitat for Humanity and WOAR.

I am currently looking for OPT (Optional Practical Training) and Full-time positions related to Design, Manufacturing, and/or Controls.

(Disclaimer: All the content of this website, apart from the platform and course projects are original work. Some CAD may be inspired by real-life examples. Please email me if you would like to reproduce them in any form).
