During September 2025, Lim Da Uto developed and delivered the Airbridge Device ID integration for the RevenueCat/purchases-android repository. This work involved implementing a new setAirbridgeDeviceID API within the Purchases class and its orchestrator, allowing the Airbridge Device ID to be stored as a subscriber attribute. Lim updated API definitions and corresponding tests to ensure seamless analytics integration, focusing on compatibility with downstream attribution and analytics workflows. Utilizing Java and Kotlin, and drawing on expertise in attribution tracking and SDK development, Lim’s contribution enhanced the SDK’s ability to capture accurate subscriber data, supporting improved marketing attribution and product analytics.
