Here is a list of some projects I've undertaken that I think might be useful.

Gitignore Modifier allows adding templates of files to ignore in a .gitignore file (for Git). The main purpose is to quickly and correctly create this file for any new project. GitHub repository

Notes-to-text is an appplication that converts iPhone Notes documents to text. It allows users to "AirDrop" a document on their computer and then use its text without opening the Notes app. GitHub repository

"Power" is a keyboard layout that balances putting keys in more efficient places compared to a QWERTY keyboard layout and the number of changes required to remember. GitHub repository

WebSSON is a data language that can represent complex data structures in a human-readable format, with less clutter than JSON and XML. The original aim was also to build a language called WebSS that'd unify various languages' syntax idiosyncracies (and possibly concepts too), but for now only the data language is mostly complete. A proof-of-concept compiler was in the works. GitHub repository Documentation
