I am not getting response from any professors or industry. Is it end of the road for me?
In short: not knowing you or your life's goals, it is hard to make an assessment, and it is surely impossible to give an objective assessment. So the answers will be opinion-based, even from people claiming to be absoulutely objective.
It looks you are still comfortable with your time in the academia, you are open to both worlds (&quot;life in both academia and industry&quot;), which is not a good thing, in terms of employment in the private world, it is often perceived from the other side as &quot;the candidate does not know what he/she wants, he is just waiting for an opening in the academia&quot; and therefore your application ends quickly in the &quot;let's get back to this later, i.e. never&quot; folder.
This even if you do not express it explicitly, the fact that you are still employed by the uni usually raises red flag for many recruiting.
Formally, it looks like you have a strong academic CV, but it is time to be independent, which means to gather your own funds (for example this Canadian fellowship https://banting.fellowships-bourses.gc.ca/ ) and to perform some research without the influence/guidance/support/involvement of your advisor.
Please note that the +-4 years contract (and associated safety of your position) you had during your PhD is the most stable position you could have had in Academia, apart from being a full professor, which may happen at the earliest some 15 years from now.
So the insecure feeling you have about academic positions, fundings etcetc in the Academia is quite common (not that I approve, but it is beyond the individual possibilities to change this). Either you:

embrace it, looking for academic/research opportunities all over the world, both in terms of open positions and grants applications;
you escape it by working independently as a consultant, or finding an industry position you like.

Final note regarding academic applications: professors are not answering to you. Why? you are very expensive, with the funding of a postdoc they can have 2 PhDs, so PostDocs positions are rare, and if they are available there is not much time to be spent thinking on it, there will be an (official) opening and it will be filled as fast as possible and with as less efforts as possible. But professor will welcome the opportunity to have more fundings, so if you ask support in writing applications for grants and external fundings you will see a better response ratio.
