This is by far my favorite programming language today! I use it whenever possible and am highly excited about its upcoming multiplatform capabilities and WebAssembly support! I've built several back-ends, and maintain multiple open source libraries. I've worked a lot with coroutines, multiplatform (JVM & Native) and Ktor.

Well, I've been using it for 20 years and quite a lot. What to say about that? It's HTML & CSS! Esp. the latter has a vaaast amount of functionality by now and nobody knows all of it. (If someone says they do… they don't!). I've used both quite extensively so I'm quite advanced at using both. Don't ask me about flex-box though – I can never remember its vast amount of properties and values and have to google it myself again and again…

I've used it a lot, enjoyed it a lot and hated it a lot. That's what you do with JavaScript :) I'm a bit out of touch with recent language improvements though since I prefer TypeScript for web projects nowadays.

I've participated in several Android app projects and know the fundamentals of the platform, UI, other related frameworks and tooling. I've debugged applications down to deep inside Android source code. I'm a big fan of Android as a user since the beginning and prefer my Google Pixel phones over iPhones anytime :)

I've built several iOS apps of various sizes over the years and loved being involved in the open language development process. I've reported dozens of crashes and other language issues back in the early days. It was a lot of fun and is a great language! I also maintain an open source general-purpose iOS development library that I use in all app projects. It's not documented though and uses private API to provide certain (but really good) functionality. I'm aware of the dragons though :)

My favorite solution for deploying websites and back-ends. It's simple, stable and suitable for most projects. I recommen simple whenever possible :) It has plenty of features though, thanks to its add-on market, and I don't know them all…

I've been using it for iOS app development for 7 years. Since I've known a lot about C++ when I started using Objective-C in 2009 it was quite easy to me to use the language as manual memory management wasn't new to me and I know a lot about debugging and disassembling by then. The language, although old, served me well in many iOS projects. May you rest in peace! Over time I've migrated everything to Swift and highly recommend to avoid Objective-C if possible. I still know a lot about the language and its dynamic runtime though, which still underpins Swift to date.
