Octavian-Ionut Neagoe

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.
• Scripts for cross-account AWS data aggregation using organization-wide IAM role assumption, integrated into a Dockerized internal web application.

Internal Projects and Tooling:

• Collaborated with development teams to build a platform for collecting and displaying multi-account AWS data in a web interface.
• Deployed on-premise Prowler containers for automated cloud security and compliance checks, integrating them into the existing infrastructure.

Collaboration and communication:

• Worked closely with development teams and clients to ensure smooth operations, using Jira for task and incident tracking.
• Responded to monitoring alerts from Nagios and handled on-call duties (24/7 rotation), prioritizing and resolving incidents under high-pressure conditions.

• 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.
