For confidentiality, I cannot disclose any of my work products done for my employer (but under "details" you'll find essays about the work and used technologies). However, all of my open source contributions are freely accessible. As most of them are related to my professional work, or even done in the context of it, they pretty accurately showcase my professionalism and capabilities.
Here's a range of my work products:
- Though I follow and participate in many lists and communities, my collaboration can probably best seen in my Stack Overflow account.
- With the Todo.txt-cli task-management productivity tool, I contributed to an established project, and gradually became the main contributor, working closely with the initator of the project, Gina Trapani.
- One of my early plugins for the Vim editor is writebackupVersionControl. I started development in Oct-2006, and published the first version in Mar-2007. As of Aug-2012, it's been through 20 releases and 3 major revisions. Though the implementation language, Vimscript, may not mean anything to you, it shows the documentation effort and ongoing maintenance.
