my current tech stack for most private (web) projects:
* [kotlin] ([programming_language])
* [gradle] ([build_system])
* [postgresql], [sqlite] ([database])
* [javalin] ([web_framework])
* [tempolin] (templating system)
* [scovy] (for database access, a bit like a simpler [jOOQ])
* [caddy] (reverse proxy, instead of [nginx])
