Bio
As a back-end developer, Dario takes pride in writing maintainable, succinct code, and he cares about automating things (CI and deployment). He's a huge fan of functional programming; he has coded in Haskell, Clojure, and other languages. He values FP because of how it helps to reason about code and write correct programs.

Experience
Pew
https://github.com/berdario/pewA rewrite of virtualenvwrapper in pure Python. What I'm fond of is also the fact that I've been able to reuse the test suite from the original project.
Managemytime
https://github.com/berdario/managemytimeA demo project, showcasing a typesafe REST API in Haskell. (And some JavaScript+HTML as UI/front-end)
Mutagen Python3 Porting
https://github.com/berdario/mutagenMy porting to Python3 of this library that deals with audio file metadata. I've made mistakes while porting, but it was satisfying to see the test cases pass on both Python versions.
Strings -n Implemented in 3 Lines of Python
https://gist.github.com/berdario/114b2daf9b43fe924676Not enough young developers are aware of mmap and end up re-implementing (poorly and less efficiently) incremental file reading when it's not really needed.
fulltextindex.hs
https://gist.github.com/berdario/6b89008b0b668df91270A simple text index/full text search in Haskell. A simple, but non-trivial example of the power of higher order functions.
RegEx Unfolder
https://github.com/berdario/regexp-unfolderThis is a small Clojure project (just 100 lines), leveraging instaparse and Clojure core.logic. It defines a relationship between a RegEx FSM and the matching strings, letting you enumerate the strings that can match certain RegEx.
