Accomplishments at Amazon
Vector Database with Amazon OpenSearch
Satyanand designed and implemented a vector database utilizing Amazon OpenSearch, capable of housing 20 billion product embeddings from a fine-tuned OpenAI CLIP model. This solution enables the identification of infringing products by correlating images with text descriptions, capturing intricate visual and textual features for highly accurate searches. This innovation has significantly streamlined counterfeit detection, safeguarding intellectual property on a large scale.
BLIP-2 Integration for Enhanced Brand Protection
He led the integration of “BLIP-2: Bootstrapping Language-Image Pre-training with Frozen Image Encoders and Large Language Models” into Amazon’s brand protection framework. This reduced the need for human audits by 80%, leveraging BLIP-2’s sophisticated image and language analysis capabilities. This integration not only improved the detection and categorization of infringing products but also enhanced Amazon’s ability to protect intellectual property, reducing brand risk effectively.
RoBERTa for IP Detection
Satyanand spearheaded the integration of “RoBERTa: A Robustly Optimized BERT Pretraining Approach” into Amazon’s IP detection ecosystem. This advanced Named Entity Recognition tool significantly improved the accuracy in detecting trademark infringements in product listings. With enhanced precision, the process of identifying IP violations became more efficient, reinforcing Amazon’s commitment to protecting intellectual property rights.
Anomaly Detection Framework
He developed an anomaly detection framework using key signals such as sales trends, the number of sellers, brand presence, type of infringement, and brand-specific IP concerns. This framework has successfully reduced false positives, minimizing the impact on sellers while ensuring that true cases of infringement are addressed promptly.
Prior Achievements at Amazon
ASIN Hijacking Abuse Identification System
As an SDE II, Satyanand orchestrated the development of an advanced XGBOOST model-based system to detect ASIN hijacking abuse. This system evaluated 25 million ASIN families daily, analyzing over 60 features to identify review manipulation. The robust system significantly enhanced Amazon’s defenses against deceptive practices, ensuring fairness in the marketplace and maintaining the integrity of the review system.
Reviews Abuse System Enhancement
During his tenure as an SDE II, he played a pivotal role in upgrading Amazon’s global review abuse evaluation system, impacting 25 countries. By designing sophisticated algorithms for real-time product listing monitoring, he optimized the system’s processing capabilities to handle 30,000 transactions per second. This proactive measure strengthened consumer trust by efficiently mitigating fraudulent review activities.
Infringing Contributor Identification System
Satyanand led the design and implementation of a system that identifies ASIN infringements for internal enforcement teams. Capable of scrutinizing 1 million ASINs per day, this system detects infringing updates among thousands of sellers, supporting enforcement actions to protect marketplace integrity.
Early Contributions at Amazon
Pay by Invoice System
As an SDE I, he contributed significantly to enhancing Amazon’s Pay by Invoice (PBI) capabilities by implementing issuer accounts and facilitating Amazon entities to leverage Cimarron’s services. His efforts ensured compliance with the Sarbanes-Oxley Act, as he architected a reliable system to capture all financial events into Amazon’s financial ledger.
