Steps you need to follow to start working as freelancer Mechanical Engineer.
find an area that interests you the most, for example, I love doing CAD designs and DIY projects.
Try to be a part of projects, I would prefer open-source projects where you can contribute your part. By doing this you will learn practical knowledge and experience Because just having the curriculum knowledge is not sufficient.
It is very necessary that start working and building your portfolio. Because the portfolio is the only thing that you will be able to share with your leads/clients to expose your experience and skills.
There are lots of platforms where you can create your profile and start your freelance career. All of them work differently so choose wisely
Try to build your presence on all the available social media platforms and be active on a few of the famous platforms like LinkedIn, Facebook, Instagram, Twitter, etc.
Always try to deliver on or before time without compromising the work quality. Because quality is everything, once you start delivering quality work to your clients they will the returning customer to your freelancing business.
Beware of the spam project/clients. And avoid those clients whose profile is not verified or if someone is asking you to contact them outside the platform.
When you are done with your project and received the milestone/payment, do not forget to ask for a review of the experience you had with the client.
