Operations and Incident Management:

• •

Monitored and maintained multiple AWS-based workflows, leveraging services such as Lambda, SNS, SQS, DynamoDB, EC2, ECS, and Docker. Investigated workflow failures using internal application logs and AWS CloudWatch, performing root cause analysis, and applying fixes. Managed change requests (CRs) involving service restarts, shutdowns, and pipeline executions (manual and automated) via Jenkins.

• • Performed daily deployments using Jenkins pipelines or via Ops-box tooling (e.g., Mockbird).

• • Managed Linux-based VMs, including disk space monitoring, file system adjustments, and workflow initiation tasks. Automation and scripting:

• • Developed Bash scripts to streamline repetitive operational tasks, including partial automation of on-prem access workflows via bastion hosts.

• • Created Python automation tools, including: an AWS cost reporting Lambda function that queried account-specific billing data and automated monthly email delivery via SES and EventBridge.

• • Cloud Infrastructure Optimization: Led efforts to optimize cloud infrastructure, resulting in a 30% cost reduction through the implementation of best practices such as rightsizing and scheduling.

• • CI/CD Pipeline Development: Developed and maintained CI/CD pipelines using Jenkins and Docker, reducing deployment times by 40% and improving the overall reliability of production releases.

• • Security Implementation: Ensured cloud security by applying IAM role-based access controls,

encryption (SSL/TLS), and security group hardening. Infrastructure Automation: Created Infrastructure as Code (IaC) solutions using Terraform to automate environment provisioning and configuration management.

• • Cross-Functional Collaboration: Collaborated closely with developers, QA teams, and operations to troubleshoot issues.

• • Managed AWS infrastructure for client projects, focusing on designing scalable, secure and cost effective solutions using Terraform.

• • Developed reusable Terraform modules for various AWS resources, enabling faster deployment and consistency across environments.

• • Created and managed Lambda functions using Python for automating tasks such as backups and monitoring.

• • Performed system administration on both Linux and Windows servers, including patch management, security hardening, and troubleshooting.

• • Implemented Docker-based containerization across multiple applications, improving consistency between development and production environments.

• • Deployed and managed a Mesh VPN using Headscale, improving secure communication between distributed systems across cloud environments, enhancing network security and reducing latency.
