    Liu played a key role in developing Uber's Backend Integration Testing Strategy (BITS), which enables on-demand deployment and routing to test sandboxes for individual code commits.1 This system has significantly improved Uber's testing capabilities, allowing thousands of end-to-end tests to run with a high pass rate before code is deployed.1

    Prior to his current role, Liu worked on Uber's Fulfillment Re-architecture, where he developed the Composable Testing Framework (CTF), a code-level DSL for modeling complex testing scenarios.1

    Liu's work has contributed to a 71% reduction in incidents per 1,000 code changes at Uber in 2023.1 His LinkedIn profile indicates he is based in the San Francisco Bay Area and has over 500 connections.2
