Romain Viallard - Functional software developer

Hey there, welcome to my blog !

I'm Romain, a software developer based in Lyon, France.

I love building tools that make people's lives easier !

I'm well versed in the usual suspects of functional programming like Haskell, Nix, JavaScript, recently also exploring the Elixir/Erlang universe. I'm also proficient in PHP as that's what I've used as an employed developer so far, mostly working on legacy ecommerce systems.

I'm currently looking for freelance contracting work.
