Hi, I'm Nikos Baxevanis.

I'm a self-employed programmer and software architect based in Zlín, Czech Republic.

Notable side projects

• Founding member and contributor to Hedgehog, a property-based testing system, in the spirit of QuickCheck.
• Pure Haskell and F# implementation of SplitMix, splittable pseudorandom number generator—passes all dieharder tests.
  Port of Guy L. Steele, Jr., Doug Lea, Christine H. Flood Fast splittable pseudorandom number generators Comm ACM, 49(10), Oct 2014, pp453-472.
• One of the oldest contributors to AutoFixture, a testing system that makes it easier to write unit tests.
  AutoFixture integrates with xUnit.net, Moq, NSubstitute, FakeItEasy, and other .NET testing tools.
• Fare, allows you to generate random text that is guaranteed to match a regular expression passed in.
  Port of Java dk.brics.automaton DFA/NFA (finite-state automata) implementation and xeger.
• Doctest, helps you test interactive F# examples, similar to doctest in Python. Built primarily as an internal tool for F# Hedgehog.
• Write you some QuickCheck, a minimal version of QuickCheck v1 ported in F#.
