I'm a web developer. I work with Elixir, Ruby, and JavaScript. Elixir is my favorite because of its elegant syntax, great performance, pattern matching, and immutability. Let me help you make it your favorite too!

I've been working with Ruby for several years as a developer, architect and team leader. It's my favorite language, it's very beautiful and simple. I's really was created to 'Make programmers happy' as Matz said.

I love writing Kotlin because it has some of the power of Scala without all of the type system complexity. It is a breath of fresh air in the Java ecosystem for those of us that like the JVM but don't like Java.

I am a software architect building platforms for 3D renderings and eCommerce. Python 2 is my day to day language but I also work with Python 3 on my side projects. I am hoping to share my knowledge with people!

I'm a CS student and a python fanatic. I fell in love with python and want to help others realize how amazing it is. I think teaching is the best way to learn, so I would like to share my programming knowledge.

I've written Perl 5 for quite a while now at various $WORK, and worked on quite a few FOSS projects with it as well. I'd love to help other people on learning Perl 5, as well as learn from them along the way.

I've been working in IT for 20+ years, and Ruby is the first language I've found that I consider truly elegant. I've learned over that time that everyone is constantly learning - I hope we can learn together!

I love learning to the point I got degrees in how/why people think the way they do and how to teach them. Then I learned how to program and have been trying to teach others as often as I can. Hope I can help.

I have always been interested in Lisps since taking the SICP course in college. I love the expressiveness and conciseness of the simple syntax, and the ability to build the language upward to meet the domain.

Elixir was my first step in functional programming and since I started I am very surprised with this language, its community and the incredible capabilities that Elixir has to improve software development.

Rust is a language that feels as comfortable as the next Ruby. While I can't say I'm an expert quite yet, I've taught a university course in it, so I hope I've picked up enough skill to help beginners out.

I find Scala to be both a beautiful and useable language. I like that you can use clear and concise functional paradigms, while still enjoying the benefits of object orientation and JVM interoperability.

My first programming language was Java. At the beginning it was quite challenging to write some code that does actually make sense. After a few days however, it became easier and fun to mess around with.

I am a Java nut. While some may hate it for its (seemingly) unnecessary verbosity at times, that is one of the main reasons I love it. I've written Java as a hobby and professionally for over five years.

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).
