Development Expertise

I'm highly talented in IT Ops, DevOps and NoOps. My expertise is systems integration, server engineering, and network management. I leverage technologies to deliver trusted solutions via both best practices and security standards. I deliver efficiency and cost-effectiveness that keeps infrastructures running smoothly every day. I automate services so infrastructures are always up and responsive.

Systems Integration

I have a rich history which includes interoperability, migrations, low-level programming, reverse engineering, and technical documentation.
