• Have seen Snapdeal systems evolve from monolithic systems to SOA system. Current systems use mysql, java, spring, hibernate, mongoDB, memcache, aerospike etc. This year I took challenge of working on Fulfillment Sytem Platform of Snapdeal.
• Scaled this system to serve more than 2 billion requests daily with response time of less than 2-3 ms.
• Introduced Application Monitoring in the system using Graphite, Yammer Metrics and Grafana, to constantly check the health of the system and track important factors
• Implemented a major and much needed feature of multi-warehouse support so that an item of same seller can be delivered from multiple warehouses.
