BACKGROUND
My path started in hands-on IT and infrastructure operations: troubleshooting systems directly, diagnosing why environments break under load, and understanding the physical and operational reality beneath modern abstractions.
NOW
Translating that operational foundation into Cloud and DevOps engineering. I spend my time running structured architectural labs, writing declarative infrastructure with Terraform, and engineering automated deployment workflows.
ENGINEERING PROGRESSION
SYSTEMS→AUTOMATION→CLOUD
A deliberate progression: understanding how single machines behave, encoding that behavior into automated CI/CD pipelines, and scaling it into resilient, self-healing cloud infrastructure.
