Engineering Leadership: Led a team of 2 engineers to deliver faster, more scalable, and better code through design reviews and technical mentorship. AI-Driven Personalization: Built a complete new homepage which is completely personalized to users interaction. User Embeddings: Tracked real-time user interaction data to generate custom user embeddings to power downstream discovery. Vector Search: Executed Elasticsearch k-NN search using user embeddings to fetch highly accurate, relevant content. System Scaling: Scaled Elasticsearch infrastructure to successfully handle >100 RPS for the personalized homepage. Search & Discovery (S&D): Handled the complete S&D vertical, collaborating with the Data Science team to achieve optimal relevant scoring by doing multiple A/B testing. Observability & Alerting: Added alerting and observability on the Growth pod which was missing from it, ensuring system stability. Campaign Optimization (Supply Pod): Led the optimization of the sale campaign go-live flow, reducing the time required to process ~300 campaigns from 12 hours to 4 hours. Problem Resolution: Identified and resolved internal issues and unoptimized implementation that caused campaigns to take 2-3 minutes to go live and frequently get stuck. Reduced the go-live time to 30 seconds to 1 minute now. Data Engineering: Built GCP Pipeline from Moengage to BigQuery.

Started as a fresh graduate, mastering foundational skills, and progressively advancing to the role of Team Lead. Successfully led a team of six, overseeing project development and collaboration. Merchant Ecosystem Development: Played a pivotal role in building the entire merchant ecosystem from the ground up, including the building of different workflows and multiple microservices. System Scaling: Worked on scaling the system from handling a few tasks per minute to 4000-5000 tasks per minute. This involved resharding the database from 2 shards to 16 shards and Elasticsearch from 2 shards to 8 shards, significantly improving throughput. Elasticsearch Plugin Development: Designed and implemented an Elasticsearch plugin for replicating data across datacenters (DCs), ensuring high availability and fault tolerance. Disaster Recovery: Led disaster recovery drills for services under my ownership, including critical storage systems (DB, Elasticsearch, AS, RMQ), ensuring business continuity during outages. Leadership & Guidance: Led a team of six engineers for over 2.5 years, fostering a collaborative environment while guiding them to design and deliver scalable, high-performance services.
