Project History
RemoteRetro
RemoteRetro enables teams of all shapes and sizes to conduct excellent Agile retrospectives, no matter where they are on the planet. Elixir, Phoenix, and PostgreSQL were used for the back end, and React and Redux for the front-end. I oversaw the technical and product development of the project, including design and copywriting. RemoteRetro is used by hundreds of companies across the globe.
Battleroom
https://github.com/vanderhoop/battleroomBattleroom is a REPL designed to help novice Ruby programmers build muscle memory for working with variables, manipulating data structures, and defining and invoking methods. I built it when I was a boot camp instructor to help students who needed extra repetitions with the basics.
slender_channel
https://github.com/vanderhoop/slender_channelslender_channel is a small, dependency-free Elixir module that exposes helpful macros for working with Phoenix Channels. I built the functionality while working on RemoteRetro.org, as I noticed a lot of needless duplication in our channels. I then extracted it into an open-source Hex package for other Elixir/Phoenix developers to use.
