Ensure high availability, reliability, and performance across both compute and data layers.
  • Proactive Monitoring & Performance Optimization: Continuously monitor system and database performance, identify bottlenecks, and implement tuning measures across distributed data clusters and Linux environments.
  • Troubleshoot Distributed Systems: Diagnose and resolve complex issues within distributed databases, Linux servers, and cloud infrastructure—ensuring stable, scalable, and resilient operations.
  • Automate with IaC: Increase efficiency through Infrastructure-as-Code (IaC) using tools like Ansible, automating database operations, cluster provisioning, and configuration management.
  • Collaborate Across Teams: Work closely with cross-functional teams to optimize, scale, and evolve infrastructure and database systems for internal services and customer-facing platforms.
  • Guide & Support: Provide expert guidance to colleagues and customers on database best practices, system performance, and scalable architecture patterns—ensuring smooth cloud and data operations internationally.
