I search for job remote on dotnet applications

Building your public profile is the first thing you want to focus on if you are looking for remote jobs. Once you have established yourself as an authority and expert in the field (.NET and .NET Core in this case), it will be easier for you to get a freelance job. The biggest challenge with freelancing is a company may not know what you can do. Here are some things to improve on:

1. Communication skills, both speaking and writing. This is very important.
2. Create a profile on public community websites like C# Corner, GitHub, LinkedIn, Medium etc. 
3. Write blogs, create videos, and help forum questions to gain a reputation on your profile 
4. Speak at user groups, events, podcasts and conferences
5. Write an eBook

After that, you can start contacting people who are hiring. It will be much easier to get work that way.

Cheers!
