Challenge: Faced with the need to ensure secure, seamless data migration across AWS regions, manage complex multi-environment cloud infrastructure, and maintain high availability for critical systems. Additionally, challenges included maintaining compliance with industry standards, reducing rising cloud storage costs, ensuring disaster recovery readiness, and improving operational response through knowledge sharing. Manual infrastructure setup, lack of standardized internal processes, and the demand for scalable, resilient architectures further added to operational complexity.

Action: Addressed these challenges by managing RDS backups/restores via S3, and migrating EC2 and RDS databases using both shared and unique KMS keys. Enforced IAM policies and AWS security best practices, while implementing proactive monitoring through CloudWatch. Automated infrastructure provisioning using Terraform and CloudFormation for EC2, RDS, Lambda, EKS, and KMS resources. Developed EC2 SQL Server backup strategies using AMIs, snapshots, and lifecycle policies. Delivered 24/7 production support for AWS and Linux environments, and led internal training sessions to streamline AWS operations. Implemented automated S3 lifecycle policies for cost efficiency, collaborated with cross-functional teams to design scalable solutions, and conducted regular audits and risk assessments to ensure compliance.

Result: These initiatives resulted in seamless, zero-data-loss migrations with minimal downtime, a 30% reduction in security incidents, and a 40% decrease in infrastructure deployment time. Achieved 99.9% uptime in production environments, improved disaster recovery, and recovery time objectives (RTO), and increased support resolution speed by 10%. Significantly reduced monthly cloud storage costs while maintaining service quality, delivered scalable architectures aligned with business growth, and ensured full compliance in all internal and external audits.
