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.

• 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%.
