Resigned without holding any offer

Hi everyone, I resigned two days ago and am currently serving my notice period. I have 3.4 years of experience at TCS, worked as a Frontend Developer, with good hands-on experience in backend development as well.

I've been applying to many companies through their careers pages over the past 1–2 months but haven’t received any responses. I would really appreciate any suggestions on how to get referrals—or if anyone is open to referring me, that would be a great help. Thanks
