I'm not an expert, but I think it all comes down to the article age. Everything is very fresh. Most content seem to be 60-90 days young.
Now a days it can take a couple of months before getting any traction.
Also it doesn't seem like you are targeting easy keywords. The websites you are competing with are big websites with a lot of trust.
My advise would be to relax. Post some more content and try to interlink all your posts. It can take 4-6 months to get some traffic. Your URL is short, nice and brandable. Your website has a clean and fast design. I like it man, but don't be too stressed. It takes a long time to get Google traffic. And try to aim for some eaasier keywords in the beginning.
Once again I'm not expert and I just did a quick look at your website and put it into Ahrefs. So don't take my words as an absolut truth.
