Hi.

I'm Alex Rønne Petersen, a self-proclaimed software engineer currently situated in Denmark.

I like to work on open source projects, particularly ones relating to programming languages, compilers, virtual machines, and garbage collectors. I'm also interested in concurrency and server-side engineering. I do some occasional reverse engineering and game programming too.

You may have noticed how I didn't list web development. Well, this site in and of itself should explain why. But fear not! I know how to link to other things on the web, so the links below may be useful if you're looking for information about me or what I do:

• Blog
• GitHub
• Twitter
• Google+
• Stack Overflow
• Quora
• Resume

I have created several open source programs and projects, some of them more complete than others:

• Flect: A pragmatic, functional systems programming language
• DAREPL: An interactive REPL for CPU architecture emulation
• ExoCore: An exokernel written in C11 (with GNU extensions) for Clang
• Genesis: The Terragenesis server, written in Elixir for Erlang/OTP
• libffi-d: Binding to the libffi foreign function interface library for the D programming language
• libmono-d: Binding to the Mono embedding API for the D programming language
• libgc-d: Binding to the libgc garbage collection library for the D programming language
• MCI: The Managed Compiler Infrastructure is a modern and intuitive compiler back end for managed languages
• PGen: Safe prime number generator written in C99 with OpenSSL
• sdb-cli: Command line interface to the Mono soft debugger
• SL#: Runtime IL-to-shader translation engine for C#/.NET

And contributed to many others:

• DMD
• DRuntime
• Elixir
• GDC
• Homebrew
• LDC
• LuaD
• Mono
• Mono.GameMath
• MonoDevelop
• MonoMac
• Pegged
• Phabricator
• Phobos
• Relex
• Rust
• VapourSynth
• Waf

These days I spend most of my spare time effort on developing and maintaining the various projects under the Lycus Foundation umbrella as well as its infrastructure.

You can reach me via email. Use alex at alexrp dot com for personal stuff and alex at lycus dot org for anything related to my open source work and projects.

If you prefer IRC, you can find me on OFTC (#lycus, #flect, #mci, #exvm, #cursive, #llvm), Freenode (#d, #d.gdc, #ldc, #proglangdesign, ##fsharp, #erlang, #erlounge, #elixir-lang, #riak, #phabricator, #nimrod, #waf, #xomb, #osdev), Mozilla (#rust, #jsapi, #ionmonkey), QuakeNet (#c#), and GIMPNet (#mono, #monodev, #cecil, #monodevelop, #xamarin, #monosoc, #monodevelop-dev). I typically go by alexrp or Zor.
