Hello,

You can try for work opportunities by joining sites like truelance, upwork, freelancer to name a few, and there are job portals like linkedin, naukri.com, indeed etc, I would say join linkedin, connect with people in your domain, follow them to know the various aspects of your domain in more detailed manner, this will help you tremendously, also a big part of freelancing is marketing your skills, so have a strong presence in social media, and build up your profile accordingly, if you're just a fresher then you may take up internships, this is important from the perspective of learning, all the knowledge which you have gained in your course you can put it to good use, and gain an understanding through its applications, you can also consider teaching through Youtube or any other way if  you're interested and confident about your skills, so basically start with whatever opportunity you're getting as it will be a stepping stone towards your success in future and continue with your efforts in steady manner.
