   Oversaw the Commerce Ads infrastructure team of 10+ engineers, managing catalog ingestion, user intent processing, and ad delivery systems. Led multiple large-scale system overhauls that optimized compute allocation and enabled independent strategy iteration, supporting 10%+ product penetration growth.• Initiated and led the department-level Experimentation Ecosystem workstream for signal, identity, and attribution to improve iteration velocity and quantify business value. Launched Shadow and Holdout experiment frameworks and expanded coverage to labels, features, and intents, The frameworks now support hundreds of experiments quarterly as a core data iteration tool.• Pioneered the Signal Data Foundation initiative focused on signal integrity and utilization. Led a team of 4-6 engineers to establish signal-feature pipelines and cleansed identity matching results, which produced a 15-20% advertiser value lift, introduced replay-capable signal storage in the data lake, and established the Golden Sequence as a unified source for feature engineering and generative recommendation research.• Designed and developed key post-delivery systems including the Label Service (centralizing organization-level positive label definitions), Dedup Service (standardizing deduplication strategies with zero-code integration), and Signal Retrieval Service (enabling privacy-preserving on-device attribution and training). These systems collectively drove double-digit advertiser value growth and streamlined collaboration across engineering, product, and client teams.
