Prasanna Narmeta

As a Site Reliability Engineer Lead/Manager, I was responsible for ensuring the reliability, availability, and performance of global infrastructure and services, particularly within the xIAM (Identity and Access Management) project. This project involved managing and securing user identities across various platforms and systems, ensuring seamless and secure access management at a global scale. My focus was on maintaining scalable, fault-tolerant systems capable of supporting high traffic volumes while minimizing downtime, as well as automating key processes to enhance system reliability and performance.

Responsibilities

• Incident Management: Led incident response for xIAM services, swiftly resolving critical issues to minimize user impact and ensure the security and availability of identity data.
• Performance Monitoring: Continuously monitored and optimized the performance of global identity systems, proactively addressing potential bottlenecks to ensure seamless user access.
• Automation: Developed and enhanced automation tools for deployment, configuration management, and monitoring of xIAM infrastructure, improving system reliability and reducing manual errors.
• Scalability & Capacity Planning: Collaborated with cross-functional teams to scale xIAM systems globally, ensuring the infrastructure could handle increasing demands while maintaining high security standards.
• Failover: Designed and implemented failover across region to region strategies to ensure uninterrupted user access and data security in case of infrastructure failures.
• Cost Management: Analyzed and implemented cost-saving measures for xIAM infrastructure, including optimizing failover and backup site configurations to balance reliability and operational costs.
• Collaboration: Worked closely with development teams to integrate identity management best practices into xIAM, ensuring resilient, secure, and compliant application designs.
• Documentation: Created and maintained comprehensive documentation for global identity management systems, including architectural diagrams, security protocols, and operational procedures.
• Mentoring & Leadership: Provided leadership and mentorship to junior SREs, cultivating a culture of reliability and security within the xIAM team, and supporting professional growth.
• Other Duties: Managed other infrastructure and reliability tasks as needed, contributing to the ongoing success and evolution of xIAM global identity and access management platform
