Welcome to my blog/online portfolio. I am Arulselvi ‘Selvi’ Selvaraja,and I am a Mechanical Engineer.

I enjoy working on innovative projects that have the potential to create a positive impact on people’s lives. I have three years of experience in Product Design and Development, Design for Manufacturing, and Project Management. I have also dabbled in different areas within Mechanical Engineering, and have multiple internships, and project and research experiences.

I want to work for organizations and with people who have a burning desire to change the world and make it better in their own way. So, if you’re part of 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!
