about

I'm an SRE with 7+ years across DevOps and SRE roles, focused on building and running reliable, cost-efficient systems. My core stack is Kubernetes, Terraform, GCP, AWS and Linux. Along the way I've cut cloud costs (COGS), improved resource allocation and made infrastructure more repeatable and automated.

Much of that came from committing to Infrastructure-as-Code. Keeping Terraform state in sync, speeding up plan runs and avoiding drift-related incidents made day-to-day operations calmer and safer. I rely on well-defined SLOs and SLIs to keep performance aligned with what the business needs.

I work closely with other engineers and share what I learn. I run on Agile with Jira, keep things pragmatic, and try to leave every system a bit more boring and predictable than I found it.
