Hi! I am Aayush. I am a free and open source software developer, mostly focused in the domain of Android development. I am an active speaker at conferences and meetups as well. When not working, you can find me either playing games on my Steam Deck or learning languages.

You can find my work/speaker/community-related things below. If something needs to be added/outdated, or you have any questions, please feel free to contact me.

Active Projects

As an active freelancer and independent contractor, I have worked on many Android-related projects during my last few years. Some of the projects that I currently work on professionally as well as voluntarily are (public available):

• Aurora Store: Aurora Store is an unofficial FOSS client to Google’s Play Store.

• CCIP-KMP: CCIP (Community Checkin with Interactivity Project) a.k.a OPass, is Taiwan’s FLOSS conference check-in solution and provides the newest event information for the audience.

• Panic: Panic is an app that allows users to uninstall selected apps & run certain actions when a system-wide panic intent is triggered. It leverages the Guardian Project’s PanicKit library for working with panic and related intents.

• Bellis: Bellis is a work profile owner application allowing users to create and manage new work profiles easily. It was initially based on the sample applications provided by Google but has been completely rewritten in Kotlin and Material3 themes.

• SystemUpdater: SystemUpdater is an updater app based on the sample application provided by AOSP. It is supposed to be used by CalyxOS to provide OTA to production devices soon.

A complete list of active/in-active projects can be found on my LinkedIn.
