TikTok, Senior Software Engineer@TikTok Social

Android developer at ByteDance, built the offline anti-degradation system from scratch and worked on platform stability and performance improvements. Recently focused on scaling Jetpack Compose adoption and building monitoring, measurement, and tuning workflows to ensure high performance in large, high-traffic Android projects.

From Debugging to Real-World Tuning: A Practical Guide to Compose Performance

How can we achieve performance for Jetpack Compose that is monitorable, measurable, replicable, and sustainably improved in an ultra-large-scale Android project with tens of millions of DAUs and thousands of collaborating developers? In this talk, we will draw on real-world business scenarios from TikTok to share our methodology and implementation for achieving this goal: 1. quickly expose bottlenecks and pinpoint issues during the debugging stage 2. build a unified performance measurement and monitoring system to make data-driven decisions 3. engineer and standardize optimization approaches and integrate them into daily development workflows 4. leverage reusable tools and practices to scale performance improvements from isolated cases to the entire team and codebase.
