Devops architect

Northland

I am a competent Linux systems professional with over a decade of experience architecting production HA systems, always working above and beyond to achieve technical purity and superiority while using industry standards and reusable, proven tooling. I understand both sides of the security coin, both testing a system for its potential weaknesses and monitoring it for all eventualities. I have always believed and practiced automation for the benefits it provides in reliability, security and scalability. From well-written perl scripts in the 90s; to using: puppet, git, r10k, containers, ansible and other current devops tooling; I strive to provide good value to operations and development teams by building IaS and PaS CD (continuous delivery) pipelines which produce excellent software products.
