Search Platform Migration
- Migrated the Search Platform from a batch-based (V2) architecture to a real-time streaming (V3) pipeline using Java, Spring Boot, Kafka, and Elasticsearch, enabling continuous alert indexing and reducing processing latency from hours to near real time.
- Designed a dual-indexing solution for surveillance and review indices, resolving out-of-order event processing through version-based indexing while ensuring data consistency and backward compatibility.
- Built an event-driven DHC Reporting pipeline using Kafka, Debezium (CDC), Spring Boot, and scheduled jobs to automate daily operational reports for enterprise stakeholders.
- Implemented ShedLock for distributed scheduled jobs, preventing race conditions and duplicate executions across multi-pod deployments.
- Led the adoption of Pact for REST APIs and Kafka event contracts, ensuring backward compatibility across independently deployed microservices.
- Integrated Pact Broker, can-i-deploy, and record-deployment into the CI/CD pipeline, improving deployment reliability and reducing integration risks.
- Implemented Datadog monitors and alerts using Terraform, enabling proactive monitoring of pipeline SLA breaches, scheduled job failures, Debezium connectivity issues, and production errors.
- Configured P1/P2 severity-based alerts with automated Slack notifications, improving production observability and incident response.
