Build dashboards and operational alerts using Splunk, Kibana, AppDynamics, Instana, or Datadog.

Troubleshoot production issues by analyzing application logs, performance metrics, event flows, and database behavior.

Collaborate with product owners, architects, QA, database, security, and DevOps teams.

Drive application resiliency, performance improvement, cloud adoption, and engineering automation.

Strong experience with Spring Boot, Spring MVC, Spring Data, Spring Batch, and REST APIs.

Experience with Jenkins, Maven, Gradle, GitHub, SonarQube, and CI/CD.

Experience with automated unit, integration, behavioural, and performance testing.

Production-support experience using enterprise monitoring and logging tools.

Proven ability to lead technical delivery and coordinate engineering activities.

Experience With Cassandra, MariaDB, Or Other NoSQL Platforms.

Experience with Apigee or another API-management platform.
