I love Swift because of how simple and powerful the language is. I am constantly learning cool new ways of writing good Swift code as I work on an iOS app day to day.

Rust is a revolutionary language that is growing and improving fast. I am proud to have been promoting Rust in my own company leading to incredible results. It covers low-level programming while offering high-level abstractions which for systems developers, it's a blessing.

I fell in love with Common Lisp for its interactivity, metaprogramming and uniform syntax. If I have any say, it's usually my language of choice for both professional and personal projects.

I like OCaml's approach of being functional first, but allowing for escape hatches into imperative code when you really need them.

I've been developing iOS apps since the iOS 3.0 days. I learned Swift when it first released with the help of exercism.io. I enjoy helping others learning the language, I always seem to learn a bit more myself.

C++ was the second programming language I learned and it has been my favorite ever since. That has been 14 years ago. I love it for its speed and explicity.

I found about elixir on exercism and thaught it were just another ruby, dropped it because I haven't had classes, read more about it, felt in love and cut off my relationship with ruby (nearly).

I've been a programmer for over 15 years. My day-to-day lately has been JS everywhere. Everywhere. I've really gotten into functional programming in recent years, which is how I tend to write Javascript. But, it can be written in many different ways and it's all about the context.

(He/him pronouns). I've been a Ruby developer for a couple of years (since 2016ish), and I've been helped along immensely by friends and the community--I'm looking forward to paying that back! When I'm not working with code, I'm probably playing or making tabletop RPGs.
