• Worked as an SDE Intern in the Backend Engineering team. Involved in the development of the following products:
• EnergyMeter : Developed APIs and consumers from scratch for a project to show users ranking in a live class based on body movements, that produced events to calculate and store rank as cache in Redis sorted sets using RabbitMQ.
• Notifications A/B Testing : Implemented an A/B testing framework to send class reminder notifications to users by setting up cron jobs at different time intervals based on their profileIds in multiple buckets. Wrote optimized MongoDB queries to extract user data directly from the database thereby decreasing response time by a good margin.

This eliminated dependency on developers by the product team to perform similar queries multiple times, thereby increasing productivity
