At CatchProbe Intelligence Technologies, I operated a three-node Elasticsearch cluster with 33 billion documents and sub-second search. I redesigned its index mappings, shard strategy, and refresh intervals as ingestion volume grew, and cut storage costs by 20% through redundant-field trimming and retention policies.

I built multi-stage data ingestion pipelines and orchestrated workflows with Celery and RabbitMQ, adding retries, backoff, and dead-letter handling. I owned backend services end to end, from architecture and implementation through Docker deployment, Kubernetes operations, monitoring, and incident root-cause analysis.

I also developed secure Python services, REST APIs, and microservices, and wrote pytest suites for ingestion, mapping, and API layers. I want to bring my production operations experience to the OpenSearch team at Canonical.
