Flock.
Indonesia's first crypto copy-trading app: follow top traders and mirror their trades automatically.
About the project.
Flock lets users copy professional crypto traders' strategies in real time, combining live market data, social feeds, and portfolio tracking. I architected the React Native app from scratch, led the Portfolio and Leaderboard features, integrated GetStream.io activity feeds for trader discovery, and built the landing page with real-time price tickers.

The product
Flock is Indonesia's first crypto copy-trading platform: users follow professional traders and automatically mirror their trades.
The need
Copy trading was a new concept in Indonesia, so the app had to earn trust fast. Real-time prices, live portfolio values, and social feeds all had to feel instant, mostly on mid-range Android phones.
What I built
Architected the React Native app from scratch, as feature lead for Portfolio and Leaderboard.
Integrated GetStream.io activity feeds that powered trader discovery.
Tuned list rendering with memoization, pagination, and virtualization, making feed load and render roughly 40% faster.
How it landed
Smooth feeds and portfolio tracking during active trading hours, and the frontend foundation for a first-mover product in a new category.
