The people behind Exercism
Track Maintainers

Track Maintainers

Our maintainers are the lynchpins of the language tracks and exercises on Exercism.

I used to be a health economist, and am now on my way to becoming a software engineer. Exercism's Java track got me started with open source.

I love Elixir for its productivity, elegant syntax, and functional nature. I've written it professionally and for fun. I hope to help people get excited about Elixir and learn some things myself, as well.

I am a Software Engineering student from San Sebastian. I enjoy a lot reading about topics related to Java, software maintainability and web technologies. My love for TypeScript began developing web apps with Angular framework.

My first adventure in coding was creating userscripts by trial and error (many errors...). Somewhere down the line I accidentally found myself employed in my first coding role as a Perl developer, after attempting pair programming in Haskell.

I'm a career-changer from education, and I used Exercism to reinforce my skills as I made the switch. I love TypeScript for the flexibility of JS with the consistency of strongly typed languages. Maintaining the TS track has grown my appreciation for the language.

I really love Linux and Bash! I think the only reason I use a window manager is for chrome/firefox. Every other open window on my machine is a terminal.

I have been writing Java code professionally for the past 3 years and I have had a wonderful experience with it. The functional style of Java 8 took some getting used to, but it really improved my team's codebase and productivity.

I was introduced to R during my statistics undergrad in 2006 and have been trying to learn to use it properly ever since! I love the power, flexibility and expressiveness of the language, and hope I can help others to appreciate it too.

I struggled to apply R to my own PhD research data in 2013. A Science Craft grad school course finally got me started when I decided to use another, well-formated data set. Since then, I have found R to be a lifeline for data analysis and teaching myself and others one or the other programming skill :-) R may not be pretty, but it gets the job done.

I love Go for its simplicity and consistency. I also appreciate how hard the Go project is working to make the ecosystem welcoming to newcomers. I no longer maintain the Go track, but still maintain the Go tooling on Exercism.

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.

I started learning APL out of general interest, realized there was no Exercism track, and decided to make one!

I love real-world, usable examples. I'm a huge fan of being able to help others to make something work how it should with maximum performance. I especially love Rust and have written a tool called BrewStillery in it and GTK-rs.

Although Python wasn't my first -- and won't be my last -- programming language, it remains my favorite for introducing others to the joys, the pains, the infrequent ecstacies, and the occasional terrors of life before the REPL.
