Clustr

Clustr is a social productivity app for iOS and Android built around accountability through other people. Instead of tracking goals alone, users join shared goals with friends, schedule activities together, and keep each other on track through chat, calls, and check-ins. The Android app is now available on the Google Play Store.

Key Features

• Shared goals with progress tracking, attendance, and a feed of friends' activities
• Group scheduling with a drag-to-select calendar that shows everyone's busy times and flags conflicts
• Real-time chat with replies, reactions, photos, and GIFs, plus in-app voice calls
• Live map showing where friends are during an activity
• Push notifications for invites, reminders, and messages, with inline replies on Android

Full-Stack Mobile Developer

I joined this early-stage startup in August 2025 and built the group scheduling calendar, much of the chat experience, the push notification system, and the interactive onboarding tutorial. That work spanned the React Native (Expo) app and the Firebase backend (Cloud Functions, Firestore, Realtime Database), and I also handled Android release builds.
