What's your dev/tech stack?

I remember just a few years ago the typical answer would have been Ruby on Rails or PHP for web apps, sprinkled with some jQuery and that's about it. Today depending on the platform (web, android, ios, …) there are tons of frameworks, programming languages, no-code and SaaS platforms to mix and match. It is difficult to keep an overview. Would love to learn more about what _your_ tech stack looks like at the moment + anything you find noteworthy about it (e.g. I heard Swift UI is great for solo-devs/designers), bonus points for sharing what you've recently built with your stack.
