I am a Software Engineer at GitHub, working on CodeQL. Previously I worked at Tweag where I consulted for Hachi Security and Juspay. I like open-source, teaching, and all things to do with programming languages!

I maintain a number of Haskell libraries, which you can find on Hackage. Some that you might be interested in are:

• wai-rate-limit, which allows you to add rate limiting to your web applications; also available specifically for Servant.
• wai-saml2 if you are building a SAML2 Service Provider.
• logstash implements various logger backends that can write to Logstash.
• network-wait lets you wait for networked services to become available.
• moss, a client for Moss, which is a code similarity checking tool.
• c14n provides Haskell bindings for the C14N implementation (XML normalisation) in libxml2.
• time-units-types, a small library for representing time units at the type-level.
• hindley-milner is a template for when you are building a Hindley Milner derived language and want a starting point.
• hoop is an experimental library I built while studying for a PhD, which implements an object system in Haskell.

For all of my functional programming teaching materials, head over to the fpclass organisation.
