I developed my personal site - https://vladislavsorokin.com (not much content there though) with NextJS typescript markdown blog template https://github.com/vercel/next.js/tree/canary/examples/blog-...

Now I am thinking about markdown editor, because writing content in VSCode, well, its ok, especially if you copy-paste from GPT, but ideally I would like to write it on the page itself so you see immediately what you get and you don't need to run the localhost etc. I think its not really that hard to make it.
