Infrastructure roots
I started hands-on in infrastructure and support roles, learning how every server, network and ticket connects to the people relying on it. Those years built a bias for action and thorough documentation.

journey
From on-prem servers to cloud platforms
The throughline of my career is making complex systems predictable. From on-premises infrastructure to cloud-native platforms, I build with a bias for automation, documentation and long-term maintainability.
Cloud & DevOps
Architecture arrived alongside Infrastructure as Code, automation and container orchestration. I focused on repeatable processes and guardrails that enable teams instead of blocking them.
SRE mindset
Real on-call ownership shaped how I approach reliability: low-noise observability, actionable alerts and shared accountability. Fewer surprises, calmer systems.
