Cross-Platform Chat App

Solo Developer2024 – 2025Mobile Chat Application
GitHub

Overview

A WhatsApp-style cross-platform chat application with grouped messages, image preview, emoji reactions, offline support, and real-time updates.

The Problem

Building a performant, feature-rich chat app that works seamlessly across iOS and Android with offline support and real-time updates is a significant engineering challenge.

What I Built

  • Custom chat UI with grouped messages by date, image preview with zoom, and emoji reactions
  • Offline-first architecture using AsyncStorage with automatic sync on reconnect
  • Real-time features: infinite scroll, live message delivery, typing indicators
  • Performance optimization with Zustand state management and virtualized message lists
