Technologies: Android

An open-source UI toolkit built by Google that deploys to Android, iOS, web, desktop, and more.

I worked on the Flutter team for nearly two years. I spent most of that time rewriting Flutter's integration with Android to facilitate add-to-app use cases.

Super Editor – Open Source Package
I created, and continue to lead, an open source package called Super Editor. Super Editor is a toolkit for building any custom document editor and document reader with Flutter. Super Editor powers rich text editing in apps including Superlist, Clearful, Reflection, and Bringing Fire.

Super Editor is one of many open source packages maintained by my team at the Flutter Bounty Hunters.

Flutter PDF Rendering for Daylight Computers
Daylight Computers manufactures an eInk tablet. Their user interfaces are all built with Flutter. Reading PDFs is fundamental to the use of their tablet, but Flutter had no PDF renderer. I recruited a fellow expert Flutter and Android developer. Together, we built a Flutter PDF renderer, including a standalone Flutter app to inspect the operations encoded in each page of a PDF.

Ardley Mortgage Applications
Took over existing Flutter web app. Re-structured app code to greatly simplify the codebase, and prepare for more developers to be added. I recruited another developer to the team and trained her on the patterns in the project.

As far as a year removed from my time working on the project, the developer I recruited was still there, more developers were added to the team, but the practices and patterns I brought to the project were still in use.
