Experience

  • Senior Applied Scientist, Amazon Pricing (Sep 2024 – Present)

    Technical lead for a cross-functional team, re-imagining Amazon’s product price estimation strategy.

    • Developed a retrieval-augmented system for price distribution estimation using similar-product pricing signals at billion-scale across marketplaces and locales.
    • Launched an LLM-based price quality assessment system for channel-agnostic pricing.
    • Developed a hyper-parallel LLM attribute extraction pipeline achieving 90%+ inference cost reduction.
    • Guided development of a centralized MLOps hosting and deployment platform.
    • Conceptualized and implemented Evaluation Driven Science, a framework for grounding roadmap prioritization in systematic model evaluation.
  • Senior Applied Scientist (Apr 2024 – Aug 2024), Applied Scientist II (Oct 2020 – Mar 2024), Applied Scientist I (Oct 2019 – Sep 2020), Amazon Books

    • Started and led a cross-functional team to build Content Moderation solutions for Amazon Books, including:
      • Hate speech and explicit content detection: Developed multi-task, multi-instance learning (MIL) approaches to detect policy-violating content in long-context book interiors.
      • Copyright infringement detection: Designed and implemented an end-to-end, multi-stage text ranking system, including a transformer-based neural ranking model for book-pair scoring, a scalable hybrid retrieval engine combining lexical and vector search, and a near-real-time inference service processing 500M book pairs per day.

  • Research Assistant, The Ohio State University

    Worked under the supervision of Prof. Huan Sun on developing techniques for effectively utilizing clean and noisy data in natural language processing.
