Congrats!!! That is awesome news. In regards to building up your resume, I would suggest trying to get some practical experience using what you have learned. There are a lot of small companies or possibly churches that can utilize your skill set. You may need to volunteer your work and do it for free initially just so you can get something to put on your resume. You can also go to the local college/universities, a lot of times, employers will have a temporary projects that they will post at the universities. Another option is to try to get work from temporary employment agencies. They may have temporary assignments that you can put on your resume. AWS is in high demand so the employment agencies should be able to find you temporary projects that you can use to build up your resume. Additionally, there are websites online that post temporay projects for freelance work. I can't really post the websites here as I cannot really endorse a the third party websites but you can do a search at your preferred search engine for freelance work. Please feel free to post a follow-up question if I have not properly addressed your question.
I’d love to endorse/recommend you on LinkedIn if you want. All you have to do is add me as a connection. Once you do that, post a picture of your cert about passing in your feed and reference me within the original post. Once I see this, I’ll be able to recommend you for your hard work on your LinkedIn profile.
