Senior DevOps & Infrastructure Engineer

I engineer open-source business infrastructure stacks for remote SMB clients, covering email, file synchronization, chat, and collaboration. These solutions replace Google Workspace and Microsoft 365 and have reduced annual SaaS costs by 45%.

I automate server provisioning, patching, and backups across AWS and on-premise Linux using Terraform, Ansible, and Bash. I also implement Icinga, Grafana, and restic-based observability and recovery solutions, delivering 99.9% uptime, recovery point objectives below 24 hours, secure remote access, and zero-data-loss hybrid cloud migrations.

I engineered secure AWS shared development environments and HPC clusters for semiconductor and EDA engineering workloads. This reduced environment provisioning time from weeks to 30 minutes.

I designed IAM, VPC, and VPN controls for cloud and on-premise lab infrastructure, enabling secure access for more than 80 engineers. I also managed more than 2,000 Linux nodes, standardized PXE deployments, and led network upgrades that improved cross-site throughput and reduced VPN latency.

I led a four-person DevOps team and introduced Terraform and SaltStack configuration management across more than 100 servers, reducing configuration drift by 40% and improving repeatable infrastructure delivery.

I architected AWS Kubernetes and Docker microservice infrastructure with Terraform and GitLab CI/CD, increasing deployment frequency from monthly to daily. I improved monitoring with Icinga, built Greenplum BI data warehouse capabilities, and provided on-call production support with 98% SLA attainment.

I delivered more than 12 short-term cloud and Linux infrastructure contracts across AWS, Google Compute Engine, and Rackspace Cloud. All projects were completed on schedule and within budget.

I migrated six web applications from dedicated and VPS environments to cloud-native architectures, reducing average hosting costs by 30% while improving scalability and fault tolerance. I also provided emergency on-call support and resolved 95% of priority-one incidents within two hours.

I migrated legacy APIs to AWS using Ansible automation, including critical Triple J Hottest 100 endpoints that had historically failed under peak traffic.

I hardened autoscaling configurations and load tested APIs to support more than 200,000 concurrent requests with 99.99% availability during the live broadcast event. I also provisioned a cloud-based iOS build system that reduced build times from 45 to 12 minutes.

I implemented SaltStack automation for infrastructure management and application deployment across Linux and Windows servers on AWS. This reduced provisioning time by 60% and lowered manual configuration errors.

I built Jenkins CI/CD pipelines for web and print publishing systems, increasing deployment frequency from weekly releases to multiple releases per day. I also provided on-call systems administration and sustained 99.95% production uptime.

I delivered cloud and Linux systems contracts for small businesses, automating server configuration with Ansible and Bash. This reduced onboarding time from two days to four hours.

I completed five AWS and on-premise infrastructure projects with full on-time delivery and no critical outages during managed support windows. My work included Linux administration, automation, monitoring, and cloud infrastructure delivery.

I maintained web hosting and VPS infrastructure for more than 500 internal and client servers, resolving third-tier support issues while maintaining high customer satisfaction.

I automated infrastructure management using SaltStack and Git, improving configuration auditability and reducing manual change errors by 45%. I also implemented Icinga2 monitoring, limited auto-remediation, and centralized Graylog logging to improve incident detection.

I delivered cloud consulting and Linux infrastructure administration services for small and medium business clients. My work covered cloud architecture, migration, and ongoing technical support.

I designed and executed an AWS migration from a traditional VPS environment, reducing cloud spend by 25% and improving service availability to 99.9%.

I built my early career foundation through Linux and Windows hosting, technical support, data center, and systems administration roles. I supported infrastructure environments containing more than 300 servers.

I sustained 99.9% availability across managed systems and reduced configuration drift by 40% using Puppet. My responsibilities included server administration, VPS hosting, Apache, MySQL, DNS, Active Directory, hardware, desktop support, and service desk operations.
