Field Notes
Worked problems and reusable designs.
Technical case studies and reference architectures from the work Helocast does: secure agentic AI, runtime agent governance, Kubernetes data platforms, and authorization built into the system. Written engineer to engineer, light on adjectives.
Reference architectures
Reusable designs for a class of problem. The design you start from, adapted to the constraints in front of you.
Architecting a Kubernetes AI platform for CNCF conformance
A curated open-source stack mapped to all twelve CNCF AI Conformance v1.35 requirements, the certification path, and the air-gapped government configuration. AI-workload portability and the separate hardening and authorization-evidence layer, kept separate.
Reference architectureSecure agentic AI on Kubernetes in a restricted environment
Running autonomous agents on a customer-owned cluster in an air-gapped or IL-restricted setting. Cluster topology, agent gateway, identity, egress control, supply chain, and authorization evidence.
Reference architectureKubernetes-native data pipelines for security telemetry at scale
Ingesting, processing, and querying high-volume telemetry that arrives in bursts. Durable log, stream and batch paths, lag-driven autoscaling, object-store analytics, and SLOs around freshness.
Reference architectureProducing ATO evidence as a byproduct of platform engineering
Authorization evidence generated from the platform, not bolted on after. Controls as code, GitOps as an audit trail, continuous monitoring as proof, and a path to continuous ATO.
Case studies
A hard technical problem and how we solve it. Worked examples, not client testimonials.
Runtime governance for autonomous agents
The agent supply chain as an attack surface: malicious skills, tool poisoning, confused-deputy chains. Why scanning falls short, and how a policy enforcement point with behavioral scoping contains an agent where it acts.
Case studyDeploying a governed Claude-based agent workflow
How to put a Claude-based agent that takes real actions into a regulated workflow without unchecked authority. The agentic loop as the control point, human-in-the-loop gates, a prompt-injection-safe operator channel, and credential custody at egress.
Have a problem that looks like one of these?
Helocast builds these on infrastructure you already own, then trains your team and leaves. Fixed scope, fixed price, first working demo in the first quarter of the clock.
