• Designed and implemented system security and data assurance, this helped reduce cost associated with information security by $5million, and increased resilience to cyber attacks by up to 60%.
• Configures Cloud watch alarm rules for Operational and Performance Metrics for our AWS Resources and Applications, this improved Operational Performance by up to 60%, and made it easier for us to observe a single platform across multiple applications and infrastructures.
• Configured S3 events to set up automated communication Between S3 and Other AWS Services, this enhanced security by 60% through data encryption and also supported the transfer of data on SSL.
• Designed Highly Available Infrastructure using Elastic Load Balancer and Auto Scaling For web Servers, which scaled in and scales out automatically, also isolated environment by having security groups and NACLs across subnets for EC2 Instances
• Architected and implemented AWS cloud cost effective solution for non production environments, this improved cost by 65% and improved productivity level by 30%
• Worked closely with over 40 customers, 20 internal staffs,and other stakeholders to determine planning, implementation and integration of system-oriented projects, this improved Performance efficiency by 50%
• Managed and monitored all installed systems for highest level of availability, this helped save cost by uo to 60% and improved security and efficiency by 50%
• Designed for high availability and business continuity using self healing-based architectures, fail over routing Policies, multi AZ Deployment of EC2 Instances, ELB health checks, Auto Scaling, and other disaster recovery Models, this improved speed by up to 35% and Lowered cost and enhanced reliability by 40%
• Implemented AWS Systems manager management service Capabilities to automatically collect Software Inventory, apply OS patches and automate Administration Tasks, and complex work flows across our environments.
• Automatically Remediated Trusted Advisor findings using amazon cloud watch events and AWS Lambda
• Implemented AWS Organization to centrally manage multiple AWS Accounts including consolidated biling and policy based restrictions thus improving performance
• Implemented Control Tower Preventive and detective Guardrails and leveraged Account Factory Integrated with Lambda for new AWS Account Creation, Vending and setup
• I Used Python's Boto 3 available in AWS SDK to write codes in my Lambda function.

• Granting User Groups to assign permission to IAM Users
• Deleting Users who had already left or no longer work for the company out of the system
• Suggested improvements to user access request workflows
• Assisted and supported information security, systems administration and project teams with the integration of programs that intersect with user administration,
• Preserved all records that indicate changes made to access control list to facilitate audits and other investigations
• ensured compliance with related industry regulations and responded to information security audits
• Developed and documented user administration and audit practices
• performed access reviews to ensure access to resources matching the various job functions
• Updated and closed tasks associated with access management requests and meet service level targets
• Ensured Access rights are updated in a timely manner as changes occur such as termination, role changes, new systems and regulatory requirements.
• Provided user access administration training, created and disabled user's accounts as needed.
• Identified and developed role based security access to match job requirements,leveraging on the least privilege principle

•Leveraged EC2, create snapshot API call to create snapshots of EBS Volumes on scheduled intervals
•Implemented Security best practices in AWS, including multi factor authentication, access key rotation, role based permissions, enforced strong password policy, configured security groups and NACLs, S3 bucket policies and ACLs
•Setup and configured logs files for detailed monitoring and alerts notifications when changes are made.
•Implemented Identity Federation using free IPA to enable users to seamlessly connect to multiple services
•Optimized cost through reserved instances, Selection and changing of EC2 instance types on resource need, S3 storage classes and S3 lifecycle policies and ACLs

•Designed for high availability and business continuity, using self healing based architectures, fail over routing policies, multi AZ deployment of EC2 instances, ELB health checks, auto scaling and other modules based on customer’s functional and non functional requirements.
