Before this I spent ten years on cloud, DevOps, and security for media, healthtech, and logistics teams. Now I'm building Temika Cyber, and this site is where I write down what I figure out along the way.
Or say hi: LinkedIn [email protected]
I am Co-Founder of Temika Cyber, a cyber security consultancy, and have spent the last decade building and securing cloud infrastructure for companies in media, healthtech, and nationwide logistics. The job is mostly invisible. That is how it should be.
Lately the hardest problems are not human. AI agents, service accounts, and machine identities now outnumber people in the stack, hold more privilege, and answer to no one. I think we should treat them like the identities they are: scoped, credentialed, and auditable. That conviction is most of what I write about here, and what we work on at Temika Cyber. I would rather ship something a team can actually operate than something clever nobody can touch.
A few things I have built, shipped, and learned from.
Building autonomous agentic AI systems: AI that plans, uses tools, and carries multi-step work through to a finished result, with a person owning the standards and outcomes.
