My contributions to well known OSS projects

RubyGems doesn't fail when you are trying to install gem from system gem cache (see RubyGems 1.3.6 CHANGELOG).
I contributed kind of matcher and its specs to rSpec.
Puka: https://github.com/majek/puka/commit/c503c3c9fb1fba2e36a6b48d1b2956accb9413c8, https://github.com/majek/puka/commit/cce90b3e48520f8e75c29b0f5ff917b03aadf9fa
In Merb I improved ARGV parsing, terminal colours for merb.thor and I added installation from custom repozitories to merb.thor (LH #857)²⁾
I have about 20 commits to Usher router, mainly related with its Rack interface or Ruby 1.9 compatibility.
I helped to DataObjects fix compilation failure on Solaris (LH #344), basically I upgraded an existing patch for DataObjects 0.9.6.
And I also fixed Racksh to play nice with require_relative.

My Own OSS Projects

Rango is most important project I designed. It is Rack-based lightweight framework inspired by Django and Merb. It's the first and the only framework in Ruby implementing template inheritance. RubyInside.com wrote an article about Rango. Recently I extracted template-inheritance to a standalone library.
Pupu is my solution for managing assets, so it's easy to install, update or uninstall packages with JavaScript frameworks, icon sets etc. I have already packed Blueprint CSS, MooTools, autocompleter, lightbox and others.
Minitest.js is my testing framework for Node.js. It's build with testing asynchronous code in mind.
Formidable is a form builder. Forms include often very complex logic which I believe should not be part of views.
My other interesting projects are Ace, generator of static HTML sites, Nake, flexible Rake replacement and Git Deploy, deployment solution based on Git hooks. See my GitHub profile for more.

Other Activities

I have written article Why Rubyists Should Care About Messaging for RubyInside.com.
I have spoken on number of conferences such as WebExpo 2008, Ruby Manor 2009, MerbCamp 2011 and NodeCamp.eu 2011.
I have written more than 100 articles and blog posts about GNU/Linux, development, Ruby, Rails, Python and so on.
I actively educate myself, I attend a lot of conferences and programming sessions.
