Portfolio

Dyslexic Character Sheets

2009 -

dyslexic-charactersheets.com, github.com/dyslexic-charactersheets

A rich, customisable set of character sheets for Dungeons & Dragons and Pathfinder.

Users select options for the character they wish to play, as well as picking a colour and uploading a portrait. The website builds them a unique character sheet.

With thousands of options, and used by tens of thousands of players, this project is still growing. It's been translated into Spanish, Italian, Portuguese, German, French, Polish and Russian.

Every part of this project is free and open source. Worked with game publishers and third parties to ensure the project is 100% legal.

New Edition (2020-)

Open source JavaScript (ES6) Babel Node.js YAML BEM Patreon

A complete rewrite for Pathfinder Second Edition, addressing issues with the original process.

The process of creating this new edition was done entirely in public, to a published schedule, with regular engagement with patrons and followers.

Uses a data-driven design, with a YAML-based DSL for describing page layouts based on inversion-of-control. These are composited by a JavaScript library into a unique character sheet.

The library is written in modern ES6 and transpiled with Babel. It's published on NPM for any other project wishing to create character sheets.

Old Edition (2009-)

Scala Adobe Illustrator PDF iText

The original version supports three games: Pathfinder First Edition, Starfinder, and D&D 3.5.

Consists of hundreds of Illustrator / PDF files, a JSON data file and a Scala-based website which joins them together based on user input.

Translator App

A web app allowing volunteer translators for each language to work together.

Complented by a set of scripts for extracting strings from Illustrator files, and for editing files to substitute translations in bulk.
