04. Professional Journey

Senior Cloud Engineer

LTIMindtree Dec 2022 - Present Hyderabad, India
  • Designed and provisioned a secure Hub-and-Spoke network topology in OCI, establishing a central Hub VCN for unified traffic governance and isolated Spoke VCN communications.
  • Established a robust security posture by implementing OCI network firewalls for both east-west and north-south traffic, leveraging policies to meticulously control and filter network communication.
  • Automated infrastructure provisioning using OCI Resource Manager with Terraform to dramatically reduce manual effort, ensure configuration consistency, and accelerate deployment cycles.
  • Achieved cost savings of approximately $643 annually by right-sizing compute/database instances, migrating data to OCI Archive Storage, and consolidating underutilized resources.
  • Planned and executed full-stack Disaster Recovery (DR) utilizing Oracle ATP with Data Guard and Volume Group CRR, ensuring automatic failover and minimal downtime.
  • Managed complex cloud migration, moving the JD Edwards Application and database data from on-premises to Oracle Autonomous Database using Oracle Data Pump, Buckets, and GoldenGate.
  • Integrated Microsoft AD with OCI IAM to enable centralized identity management, configuring and enabling Single Sign-On (SSO) across OCI resources.
  • Enhanced observability by integrating OCI Logging and OCI Streaming with the SIEM tool IBM QRadar to centralize log data, facilitating real-time threat analysis.
  • Enforced cloud security best practices by adhering to CIS Benchmarks, National Cyber Security standards, and recommendations from OCI Cloud Guard/Advisor.
  • Governed and optimized OCI Autonomous Databases, MySQL Heat Wave, and Base DB instances, implementing regular backups and patch management.
  • Configured and supervised OCI Fast Connect and Site-to-Site VPN connections to establish secure, high-performance connectivity between on-premises and OCI.
  • Developed and maintained High-Level and Low-Level Designs (HLD/LLD) with packet flow diagrams, guaranteeing OCI tenancy architecture delivered scalability, security, and optimized performance.
  • Implemented IAM policies and structured compartments based on environment and application types to enforce security and the principle of least privilege.
  • Supported the configuration and troubleshooting of applications like FortiGate, Infoblox, Tenable, Veeam, Seclore, ELK, Splunk, Nagios, and Microsoft AD into the OCI environment.
