Welcome to my blog/online portfolio. I am Arulselvi ‘Selvi’ Selvaraja,and I am a Mechanical Engineering graduate (2019).

I enjoy working on innovative projects that have the potential to create a positive impact on people’s lives. I have dabbled in different areas within Mechanical Engineering, and I have a year of co-op experience in Design, Controls Systems and Project Management, and multiple project and research experiences.

I’m aspiring to work with organizations that deal with electro-mechanical systems, project or data optimization, and a burning desire to change the world. So, if you’re such an organization, you definitely want me on board, because you won’t find a more passionate individual than me!

During my free time, you’ll find me volunteering with the local community, snapping landscape photographs, weaving excellent and terrible poems, or exploring new cuisines. Feel free to message me if you’ve any questions or if you’d like to connect and have a chat!
