Hello Rahul,
There are many online portals in which you can create your account and put your full resume along with a sample of the works you have done or the company you have been associated with and your position and responsibility of work.
Few online portals are Internshala, freelancer.com, LinkedIn, naukri.com, indeed.com etc.
Here you will have to apply to all the companies that you wish to work for and they will shortlist the candidates according to their requirement.
Overall it's a long process and requires a lot of patience to land in a decent job.

Hope this helps,
Good Luck!
