PROFILE
Thales Lima
Over four months, contributed to the androidx/androidx repository by building a comprehensive benchmarking infrastructure for the SavedState API, focusing on serialization and deserialization performance across diverse data types. Leveraging Kotlin, Gradle, and Kotlin Serialization, developed suites to measure encode and decode efficiency for lists, arrays, and polymorphic data, enabling data-driven performance optimizations. Refactored SavedState to store Boolean lists as arrays, reducing memory overhead and improving serialization speed. Enhanced test reliability by addressing lint warnings and improving CI readiness. Also introduced a dedicated navigation3-benchmark module, establishing a foundation for ongoing performance testing and supporting robust persistence and navigation behaviors.

Aug 1, 2025Monthly summary for 2025-08 focused on feature delivery in androidx/androidx: implemented a Performance Benchmark Suite for encodeToSavedState. The work adds a benchmarking framework to evaluate encodeToSavedState performance across serializable collection types, introduces data classes for various array and list types, and integrates the Kotlin serialization plugin. Benchmarks cover lists of integers and strings and arrays of booleans, characters, doubles, floats, integers, longs, and strings. Commit included: 9c29f644ee823ea57604d72cd323daf0c11d896a - "Add SavedState Serializable Encode Benchmark".
