Side Projects


donjon provides random generators and other tools for pen-and-paper role-playing gamers. The backend is primarily written in perl, with some parts in C for performance. The frontend is a mix of Vue.js and vanilla javascript with Prototype. The site handles around 25 million requests per month.

DragonVale Sandbox

The backend is entirely written in perl, and is why I've become a fan of Devel::NYTProf. The frontend was recently rewritten from vanilla javascript into Angular. The site handles approximately 25 million requests per month, and leverages Cloudflare to handle over 450 GB of data transfer.


Brickdraft is a web app I wrote to manage set drafts for my LEGO user group. It uses Google's Cloud Firestore to synchronize state and data between an arbitrary number of participants, and Vue.js and jQuery for presentation.
