I build the parts of organizations that don't show up in the keynote — platforms, security posture, operating models, and the boring infrastructure that decides whether everything else works.
Operator first. Builder always.
I'm Andy Surujnarine — a technology leader who turns messy, high-stakes infrastructure into systems that are secure, reliable, and easier to operate. Most of what I'm proud of is unglamorous: a migration nobody noticed, controls that actually get used, a program that stops paging people at 3am.
Approach
Optimize for defensibility — technical and operational.
Evidence beats rhetoric.
Controls, telemetry, and runbooks beat aspirational architecture diagrams.
The org chart is the architecture.
How a company is wired determines what it can run safely at scale.
Discipline compounds.
Repeated execution on incidents, change, and debt beats heroics.
