Birmarket | Online marketplace

Birmarket started as Umico and grew to 2M+ customers. On the Loyalty team, built Premium Subscription and expanded it from a single feature into a full module.

  • Built marketplace features across the app in UIKit and SwiftUI, including deep-link navigation, and migrated 15+ screens from UIKit to SwiftUI.
  • Extracted feature modules and shared infrastructure into Swift packages as the team modularized the monolith, and fixed performance issues in the legacy code: memory leaks from retain cycles and UI hangs.
  • Rebuilt Premium Subscription as a Swift package SDK with SwiftUI and Clean Architecture, then shipped it in three apps: the marketplace, a banking app, and a payment wallet.
  • Reviewed code, onboarded new iOS engineers, and set up feature flags and A/B tests, among them the tests behind a new subscription onboarding that raised new-subscriber conversion to about 7-8%.
  • Took on-call crash-monitoring shifts, with the crash-free rate above 99.9%.

  • Built much of the drink customization, including client-side price calculation.
  • Owned the dynamic menu, the app's signature feature: client-side logic that built each customer's menu from the backend catalog by preference and time of day, with looping drink videos cached offline.
  • Ran App Store releases, set up the release CI pipeline, and wrote unit tests for pricing and cart state.
