ABOUT ME
Full stack developer, Java expert, Bash and Git ninja
Full stack developer, Java expert, Bash and Git ninja
I like to code and I do it a lot. I produce high quality code that's easy to understand and maintain. I enjoy mentoring programmers, I help them build a solid foundation, and set them on a path to producing high quality work. My favorite mentoring jobs are those where I learn something interesting myself.

Writing unit tests is not nearly good enough. Like code, unit tests can be written well and written poorly. Poorly written tests quickly become a maintenance nightmare. Well-written tests help you work better in every way. I can help you write better unit tests.

I've been using Bash as long as I can remember. I seek to automate repetitive tasks, and in my experience command line tools trump graphical tools almost every time. The desire to maximize productivity has naturally drove me to mastering Bash, without looking for such skill.

Git is my current choice of VCS tool and it's awesome. I've been expert of other VCS tools in the past, such as CVS, Subversion, Arch, Bazaar, until I finally ended up with Git. The VCS is the first thing I setup in any environment before writing a line of code. It's that important.

I'm fascinated by this language, and use it more and more to build portable pragmatic projects.
