A location-based social platform where short videos and images become series. I led the full re-architecture of the iOS app and its video pipeline.
The challenge
A high-scale, video-first feed has to start instantly and keep playing smoothly — including for people on constrained or unreliable networks.
My contribution
- Led the full re-architecture of the Redz iOS app.
- Optimised the multi-threaded video preloading pipeline.
- Built an offline-first data layer for a seamless experience on poor networks.
- Integrated Apple & Google subscription payments and owned end-to-end App Store release workflows.
- Helped move the team to a structured agile delivery model with CI/CD and automated releases.
