• Designed and built, high throughput (more than 500K ops) notification system responsible for sending 8 billion notifications per day to 400 million users.
• Built notifications rate limiter for controlling the volume of notifications sent to users, supporting user-personalized limits for different notification types.
• Built pipelines for integrating AI models which personalizes notification sent to users based on time and volume.
• Built User Target Service (responsible for maintaining user segments to whom notifications are targeted). Build event-driven architecture to update these segments using a lazy update strategy by utilizing GCP solutions like Log Explorer, Cloud Task, Cloud Function, and BigQuery.
• Worked on different cost optimizations
• Improving the BigQuery(data warehouse) slot consumption cost for creating user targets using uniform random load distribution, which resulted in savings of around $20K per month
• Used compression and batching techniques to improve messaging queue cost by 40%.
• Used data compression to compress certain column values which saved data storage (ScyllaDB) cost by around $3K per month.
• Optimized Monthly Active Users (MAU) storage and processing
• Reduced the processing time of the MAU data updation job from 30 hours to 3 hours by optimizing queries and data storage policies.
• Identified and resolved data storage issues, resulting in a reduction of data size from 250GB to 30GB.
• Improved the data sharding strategy for MAU, resulting in a 10x improvement in notification sending time.
• Tech: Nodejs, Express, Bigtable, Redis, GCS, PubSub, Cloud Task, Cloud Function, GCP Log Explorer, Kubernetes, Firebase Cloud Messaging, Scylla DB, Grafana
