Key Responsibility
- Design, develop, and maintain IAM and authentication microservices using Java, Spring Boot, and Spring Security.
- Work on v-Key authentication system migration from JBoss to OpenShift (OCP), including containerization, deployment strategies, and environment stabilization.
- Develop and enhance secure RESTful APIs for authentication, authorization, and transaction validation.
- Implement and maintain mobile-based Multi-Factor Authentication (MFA) and dynamic token generation for high-value transactions.
- Collaborate daily with DevOps, Infra, Security, and Support teams across regions (SG, HK, IN, ID).
- Monitor application health and performance using Grafana, ELK Stack, Graylog, and alerting dashboards.
- Perform load, stress, smoke, and performance testing using JMeter to validate scalability and resilience.
- Handle production incidents and escalations, including deep debugging and issue resolution.
- Conduct root cause analysis (RCA) for recurring or critical IAM and authentication issues.
- Participate in chaos testing exercises to validate system fault tolerance and high availability.
- Contribute to CI/CD pipelines using Jenkins, Git, Bitbucket, ensuring smooth builds and deployments.
- Maintain technical documentation, runbooks, and knowledge articles to support operations and onboarding.
