Welcome

I'm an American living in Helsinki, Finland and I like PureScript and Haskell.

Please message me on Twitter sometime if you'd like to get coffee or beers. Please try not to e-mail me.

Small notes

Most all of my blog posts are on Qiita and are almost exclusively about PureScript and Haskell.

In 2017, I wrote 30 blog posts, of which 27 had content about PureScript and 3 had content about Haskell. I plan to write at least 12 but less than 50 posts for 2018.

I was a speaker at Small FP Conf: http://clojutre.org/2017/#purescript.

I talked about the RowList type-level structure using RowToList in PureScript and its various applications. The video and slides are available in the link, or via YouTube and Speakerdeck respectively.

I was a guest in March 2017 for the podcast Functional Geekery: https://www.functionalgeekery.com/episode-88-justin-woo/.

In the episode, I awkwardly talk about my background and how I got into PureScript and evangelizing it.

In short, I went from writing Java to writing a small amount of Clojure/Clojurescript, lots of Javascript, some Elm, and then started using PureScript afterwards. I started using Haskell after I was already using PureScript, strangely enough. I also talk about some of the things I don’t like about Elm, and why I switched over to using PureScript for my compile-to-JS needs for both Node.js and browser code.

In October 2016, I prepared a blog post for the Futurice blog here: http://futurice.com/blog/making-a-weather-telegram-bot-in-purescript

The contents are fairly out of date (even as of 7 May 2017), but hopefully still somewhat interesting to read.
