RepositoryLead Developer · Remote, US
A marketplace where businesses sell through short vertical product videos. I lead the Kotlin and Swift architecture of its apps, engineered the feed's video playback with caching and preloading so videos start instantly without wasting data, and built an AI video studio for creating and editing product videos.
Launched on the App Store and Google Play with 1,000 users on day one.

Migrated the backend from Firebase to a REST API, then led a full UI and UX redesign and a frontend architecture overhaul for scalability and performance. Built public lists and the monetisation system that lets creators earn from them.
The relaunch brought in ~10K new users and creators.
