About pfm

pfm is the nickname I’ve started using quite a long time ago (perhaps between 2002–2005). My real name is Piotr Mieszkowski and this is my personal wiki. I’m a software engineer interested in clean, simple and working designs. Most of the time I write Scala code, but I can also find my way around in codebases in other languages, such as Java, PHP, Common Lisp, Elixir or Perl (see some examples below).

I use GNU Emacs.

Opinions published here are my own and not of my employer.
