Lead Software Engineer:

PhonePe Ads : This is our in-house ad management platform, consists of different components of the ad funnel that make up the ad platform ecosystem at PhonePe. It powers digital ads and provides an array of efficient targeting options to display ads to relevant end users. The platform handles over 70K RPS traffic .

• Domain: We designed and oversaw the creation of a high-throughput, low-latency platform capable of serving over 70K RPS traffic . To ensure maximum efficiency, we implemented precomputation to speed up ad-selection evaluations, used asynchronous flows where appropriate and created a system adhering to microservices architecture. we also ensured all relevant metrics required for analysis and reporting were captured.
• Design Goals: Ads system has to provide high scalability, availability, low latency, efficient resource usage, Micro service architecture, Highly Resilient and high performance.
• Leading a team of 7 members.
