Senior Software Development Engineer

Oct 2015 – Present · 10 yrs 8 mos · Redmond, Washington · On-site

Driving innovation and performance at internet-scale systems, I led mission-critical initiatives across Microsoft Knowledge Graph, Bing, and Graph Search. My contributions span large-scale distributed systems, AI-powered pipelines, and system optimizations that cut latency, boosted throughput, and reduced infrastructure cost.
Graph Search Optimization: Re-architected search infrastructure using column store DB, improving query throughput by 20x and reducing latency from 200ms to 25ms.
Image Processing at Bing Scale: Designed a scalable pipeline that processes over 1B images, reducing E2E processing from 2 weeks to 24 hours, and storage by 5x.
Graph Algorithms & Publishing: Engineered a faster Graph Walk algorithm, enabling 7x faster graph publishing by optimizing traversal and compute strategies.
Real-time Streaming Platform: Developed Spark-based microservices for processing over 5M entities daily, integrating Kafka and Azure to ensure reliability and data integrity.
Storage & Compute Efficiency: Led Content Data Builder enhancements, achieving 3x speed-up and cutting data volume to 30–40% for significant cost savings.
URL Submission Platform: Scaled Bing's submission pipeline to process over 40M URLs/day, improving indexing latency and freshness of search results.
