Proficient in utilizing the AWS platform and its wide range of services to design, deploy, and manage cloud solutions. Expertise includes configuring and managing Identity and Access Management (IAM), Elastic Compute Cloud (EC2), Elastic Block Store (EBS), Virtual Private Cloud (VPC), Relational Database Service (RDS), CloudWatch for monitoring, and CloudTrail for governance. Additional hands-on experience includes the use of CloudFormation templates for automated provisioning, configuring auto-scaling groups for dynamic resource allocation, and optimizing content delivery using CloudFront. Comprehensive experience in managing Simple Storage Service (S3) buckets, Simple Queue Service (SQS), Simple Notification Service (SNS), Lambda functions for serverless computing, and DNS management with Route 53. Led the migration of Java-based applications from on-premises environments to AWS cloud services, ensuring smooth transitions and full operationalization in the cloud. This included migrating application databases, reconfiguring connections, and validating application functionality within the AWS ecosystem. Leveraged AWS-native tools and services to optimize performance, reliability, and scalability of the migrated applications, ensuring they adhered to cloud-native best practices. Developed and deployed containerized applications using Docker and orchestrated their operation within Kubernetes clusters. Specifically, deployed containerized workloads to an Amazon Elastic Kubernetes Service (EKS) cluster, ensuring high availability, scalability, and efficient resource utilization. Configured Kubernetes pods, nodes, and services, while integrating monitoring tools to oversee container health and performance.

Administered patch management and package installation on Red Hat Linux systems using RPM and YUM package managers. Regularly applied critical and security patches to maintain system stability and compliance. Coordinated the testing and deployment of software updates across multiple servers, ensuring minimal disruption to operations. Proactively identified dependencies and resolved compatibility issues during package installation, improving system reliability and performance. Deployed and managed authentication services, including Centrifydc and Winbind, on Linux systems to enable seamless integration with Active Directory servers. This setup facilitated centralized user authentication and policy enforcement, enhancing security and streamlining administrative processes. Automated the setup of Linux clients for Active Directory authentication, reducing manual configuration errors and saving time during large-scale deployments. Installed and configured Oracle Real Application Cluster (RAC) on Linux servers, ensuring high availability and performance across multiple nodes. Implemented robust automation using cron jobs to schedule regular backups, monitor system performance, and remove redundant files. This proactive approach enhanced system stability, ensured data integrity, and optimized resource usage across the cluster. Managed the configuration and administration of multiple network services, including LDAP, NFS, FTP, SAMBA, DNS, and POSTFIX servers. These services supported seamless file sharing, directory access, email communication, and centralized authentication across the network. Configured and fine-tuned these services to meet specific organizational requirements, ensuring secure and efficient operation.
