• Part of BackEnd Engineering - Notifications Engine Pod.
• Migrated the existing monolith to a new Async, Queue-based Microservice Architecture Backend, with integrated logging and API-performance metrics.
• It led to an increase of 500% in the overall clicks from the Notifications Engine. (110M notifs/day at peak).
• Rewrote Raven, our delivery and click tracking service, from the grounds up, resulting in sub-second latencies at 200K RPM and a 400% reduction in the number of invisible messages (SQS).
• Led the migration of the Read path (Notifications Panel) to a kotlin-based architecture on K8 Pods, which resulted in a 40x decrease in response time (2.5s to 60ms) even at 50K RPM, as well as a 100% reduction in app timeouts. Added application metrics for throughput, error rate, and latency.
• Led a more than $50,000 USD proof of concept with a third-party service, resulting in a 12% increase in notification delivery. Added proper metrics to monitor the given SLA.
• Participation in on-call duties for the Notif Engine (which has a peak Mongon rpm of (10K RPM Read + 4K RPM Write QPS), also responsible for mentoring two juniors.
• Added a DLQ-based, Tiered Retry pipeline to Notif Engine, thus preventing any poison pill.
• Helped build the Engineering Team by Interviewing around 40+ people for both junior and senior roles, also shadowed VP and CTO in a lot of interviews.
