Architecture for systems that have to work in the real world.

Practical thinking, open-source tools, architecture models, and experiments for engineers and technology leaders building complex software systems.

Explore production-minded guidance across software architecture, platform engineering, distributed systems, engineering strategy, and emerging AI systems.

By Jacob George — technology leader and software architect.

Start with a problem

Useful architecture starts with the decision you need to make.

Browse by the kind of system or engineering problem you are working through, then move from explanation to implementation and evidence.

When AI can take action

How should models propose tool actions without becoming the authority that executes them?

Explore governed autonomy

When signals disagree

How can distributed systems build confidence from independent evidence without mistaking repeated noise for truth?

Explore evidence-driven resilience

When engineering has to scale

How do architecture, platforms, and engineering strategy reduce friction without creating another layer of bureaucracy?

The site spans architecture and technology leadership broadly. AEG and SHIELD are flagship original work, not the boundary of the site.

Practical Resource

Govern AI tool execution instead of trusting model output

`aeg-intent-gate` is a small TypeScript approval gate for AI tool calls, MCP tools, and human-in-the-loop workflows.

Models can propose actions, while policy and approval remain outside model reasoning. Executors receive only commands that crossed the governance boundary.

Intent Gate Lifecycle

model → proposed intentpolicy → allow / block / reviewapproval → constrained commandexecutor → consequential action
Propose

Model output is treated as intent.

Govern

Independent policy decides authority.

Execute

Only approved scope reaches the tool.

Original Architecture Work

Models for evidence and authority

Two independent models explore different boundaries that become important as software grows more adaptive and autonomous.
