• As part of the monitoring and alerting platform, developed and implemented strategy to move old metric data points from old cluster to new cluster in the new data center, with minimal customer involvement. Debugged and optimized queries which at times were violating the SLA for scheduled checks performed by the alerting service.
• Lead development on the platform offered Aync Event-driven State Machine Orchestrator FLUX. Scaled the system from orchestrating 200K workflows to 2M workflows a day. Decoupled the orchestration and state execution components into independent service layers. This also offered clients to maintain their own independent state execution clusters and auto-scale as per their needs.

• Worked on the central messaging platform, system is responsible for reliable message delivery with at-least-once delivery and ordering guarantees. The system provided queue and pub-sub (topics/subscriptions) abstractions for message delivery based on push model.
• Helped in scaling the system 10X, from 5K to 50K messages on ingestion layer and 10K-100K on delivery layer, achieved this by creating sets of Kafka brokers, and pinning topic to a particular set. Added automated blacklisting on producer layer which helped in safeguarding cluster from unexpected bursts and maintain SLA. Fixed broken test suite. Added end to end integration tests and unit tests which improved overall productivity in the project and ensured bug-free releases.
• Added self serve workflows, on the web interface for CRUD operations, with auto-approvals from authorized tenants. After release, reduced daily on-call tickets by 75%.
