Sammi Leung

I am a program and product operations leader with 6+ years driving scalable operations, data quality, and process transformation across global platforms. I focus on clear process design, data-driven insights, and practical training to enable teams to perform with confidence.

At ByteDance/TikTok I owned operational strategy for POI and GIS platforms, led SOP development, and partnered cross-functionally with Product, Engineering, and Global Ops to standardize data labeling and enhance accuracy. I also led U.S. data security and e-commerce SOP development, reducing customer case escalations through targeted operational improvements.

Previously, I managed Safety Operations PMO initiatives that improved accuracy by 40%+ and sustained ~90% accuracy, and supported agent quality through targeted training, simulations, and calibration. At Google (via Tech Mahindra) I synthesized large user-feedback datasets into actionable insights using A/B testing and analytics and mentored team members to improve efficiency.

I hold a BA in Sociology with a focus on business and organizations and a Lean Six Sigma Yellow Belt. I bring a pragmatic, results-oriented approach to operations, emphasizing measurable improvements, cross-functional alignment, and scalable enablement.
