Hector Morillo Prieto contributed to the DataDog/dd-sdk-android repository by delivering configurable app versioning and enhancing time management for RUM and monitoring, enabling deterministic event timestamps and faster, more reliable CI testing. He introduced a timeProvider pattern and modernized test infrastructure using Kotlin and Gradle, which improved test speed and reliability. Hector also implemented custom view instrumentation types for cross-platform telemetry, allowing Flutter, React Native, and Unity clients to report accurate analytics. Additionally, he improved documentation in the DataDog/dd-sdk-android-gradle-plugin repository, ensuring correct issue tracking. His work demonstrated depth in Android development, CI/CD, and cross-platform SDK instrumentation.

February 2026: Delivered cross-platform instrumentation enhancements and documentation fixes to improve telemetry accuracy and developer experience across Android SDKs. Focused on business value through reliable data collection and clearer maintenance workflows.

January 2026 — DataDog/dd-sdk-android: Key features delivered include Configurable App Versioning allowing customVersion precedence via configuration, with setVersion hook and updates to DefaultAppVersionProvider. Time Management improvements introduced a timeProvider for Rum/Monitoring, enabling deterministic timestamps and faster, less flaky tests. Test infrastructure modernized with controllable time and StubSDKCore.advanceTimeBy, eliminating long sleeps and speeding CI by ~25 seconds. Notable bug fixes: stopResourceWithError behavior now uses getEventTime (time-aware) and ConfigurationForgeryFactory stores customVersion as nullable. Impact: more accurate event data, improved reliability, faster feedback loops, and greater configurability for SDK clients. Technologies demonstrated: timeProvider pattern, test doubles/mocking, deterministic testing, Kotlin/Java codebase, CI efficiency improvements.
