  • EC2 Instance Networking - VPC Protection
  • I lead initiatives to enhance EC2 instance networking congestion management using advanced data analytics from a large-scale data warehouse. I develop and implement systematic mitigations for network overload events, improving stability across AWS regions. My role involves analyzing complex customer escalations to ensure high-quality service delivery, while collaborating with sister teams on both short-term fixes and long-term strategies. Additionally, I design and implement analytics-based solutions to detect and address various congestion-related challenges, including potential DoS scenarios.

  • EC2 Instance Networking - Analytics and Insights
  • I led the development of a mission-critical dataset generation platform for the EC2 VPC organization, architecting a scalable system processing 150 terabytes daily from millions of Nitro cards and instances. I created sophisticated dashboarding services and implemented end-to-end data pipelines using Java-based Lambda functions and PySpark on EMR. This work revolutionized the organization's approach to fleet health monitoring, feature performance assessment, and customer experience measurement. By leveraging data-driven insights, it enabled strategic product decisions and significantly enhanced the team's ability to optimize service performance and respond to customer needs.

  • Bing - Conversational Search
  • I collaborated with senior applied scientists to develop an innovative search experience that changed how users refine their queries. By implementing vector embedding-based search and approximate nearest neighbor based intent matching. We created an intelligent system that guides users through an intent clarification process, transforming vague queries into precise ones. This pioneering work eliminated the need for users to manually sift through web pages, instead providing direct, inline answers when possible through an interactive conversation flow built from search session data. The system's success led to its evolution into a long-term Bing feature that continues to enhance user search experiences today.

  • Bing - IE & New Search Experiences
  • I worked on innovative prototype experiences leveraging Bing's search indexes and image technologies. I architected backend systems for applications including an XR-powered neighborhood exploration tool using Zillow data, a face-swapping application enabling virtual try-ons and conversational search experience. My work on conversational search prototypes proved so impactful that it evolved into a subsequent full-time role, demonstrating my ability to transform experimental concepts into production-ready features.
