Octavian Neagoe

Operations and Incident Management:

• Monitored and maintained multiple AWS-based workflows, leveraging 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 CI/CD pipeline executions (manual and automated) via Jenkins.
• Performed daily deployments using Jenkins pipelines or via Ops-box tooling (e.g., Mockbird).
• Administered Linux-based VMs, including disk space monitoring, file system adjustments, and workflow initiation tasks.

Automation and scripting:

• Developed Bash scripts to streamline repetitive tasks, including partial automation of on-premises access workflows via bastion hosts.
• I built Python-based automation tools, such as an AWS cost reporting Lambda function that queried account-specific billing data and automated monthly delivery via SES and EventBridge.
• Created scripts for cross-account AWS data aggregation using organization-wide IAM role assumption, integrated into a Dockerized internal web application.
• Collaborated on the design of reusable Terraform modules to standardize the provisioning of infrastructure across environments, enhancing Infrastructure as Code adoption.

Internal Projects and Tooling:

• Partnered 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 international clients to ensure smooth operations, using Jira for task and incident tracking.
• I responded to monitoring alerts from Nagios, Prometheus, and Grafana, handled 24/7 on-call duties, and resolved incidents under high-pressure conditions.

Cloud Infrastructure Optimization:

• Led initiatives to optimize AWS-based infrastructure, achieving a 30% cost reduction through best practices such as rightsizing, scheduling, and automated resource management.
• Applied cost optimization and security best practices across multiple environments.

CI/CD and Automation:

• Designed, developed, and maintained CI/CD pipelines using Jenkins and Docker, reducing deployment times by 40%, and improving release reliability.
• Implemented Infrastructure as Code (IaC) solutions using Terraform, automating environment provisioning and configuration management.
• Created and managed reusable Terraform modules for AWS resources, accelerating deployment speed, and ensuring consistency.
• Automated operational workflows with Python-based Lambda functions for tasks such as monitoring and backups.

Systems and Security:

• Performed system administration on Linux and Windows servers, including patch management, security hardening, and troubleshooting.
• Ensured security compliance via IAM role-based access controls, encryption (SSL/TLS), and hardened security groups.
• Deployed and managed a Mesh VPN (Headscale) to improve secure communication between distributed systems, reducing latency, and strengthening network security.

Containerization and orchestration:

• Implemented Docker-based containerization across applications, ensuring consistency between development and production.
• Participated in internal Kubernetes knowledge-sharing sessions and labs, gaining a theoretical understanding of cluster orchestration and scaling.

Cross-Functional Collaboration:

• Worked closely with developers, QA, and operations to troubleshoot issues and improve delivery pipelines.
