Designing the systems behind AI engineering.
The AI-native engineering practice of William Chiu.
AI Software Architect and AI Native Engineering Researcher focused on governable autonomy, durable context, and enterprise-grade delivery systems.
Best fit: AI platform strategy, architecture direction, governance advisory, research partnerships, AI adoption and team training, and product builds from MVP to launch.

Featured work
Concrete systems work across AI engineering, platforms, and UI infrastructure.
SaaS platform architecture, design-system infrastructure, and AI-assisted specification workflows.
User Platform Architecture
A SaaS platform core designed around clear client, BFF, domain, identity, notification, and integration boundaries.
Design Engine Kit
A theme-driven design system architecture for reusable SaaS interfaces, generated layouts, and defensible enterprise UI composition.
Spec Generator
A planning system that translates plain-language product intent into structured engineering specifications, phased action plans, and reviewable delivery constraints.
Philosophy
Software engineering is becoming a systems design problem for human-AI collaboration.
AI engineering is becoming an architecture discipline, not a tooling upgrade.
The durable advantage is not a better individual interaction. It is better system design around intent, context, governance, and feedback.
Autonomy must be observable before it can be trusted.
Human judgment remains the center of accountable engineering systems.

One caller, two approvers: the bypass a reader found in my approval code
A reader showed that the reference HTTP server in aine-control-plane let one caller grant itself the approver role and fill a two-person quorum by sending two names. What the fix does, what it costs, what is still open, and why a pilot's stop condition for bypassed approval depends on it.

Choosing a First AI Pilot Across Three Workflows
Choose a first AI pilot with three synthetic workflows, a reusable assessment table, clear handoffs, and a baseline that includes review and rework.

A frozen field with one witness is still a claim
A field captured at the call site and frozen, exactly by the rule, can still prove nothing, because nothing else in the record holds a value that could disagree with it. How to find the second witness for each field, the field in my own system that had none, and where a second witness goes blind.
Product builds
Product builds, from MVP to launch.
Alongside architecture advisory and AI adoption training, I deliver products end to end: scoping, architecture, mobile and web development, launch, and handover. Products that ship AI features especially need their boundaries and operations thought through up front — that is where most of my attention goes.
Scope first
What the first version does and does not do, written down before work starts.
App, web, and backend
iOS / Android, website or admin console, and the API behind them.
Launch and handover
Store review and deployment, with docs and source handed over in full.
Past work
E-commerce app and websiteClient not named
Shoppers browse products by category, place orders, and pay online from their phone or the web; the store lists products and manages categories from its own admin console. I handled the whole build: requirements and scope, app and website development, the admin backend and payment integration, through launch and ongoing maintenance.
How a build runs
- 01Discovery and MVP scope (written)
- 02Design and architecture
- 03Build, with a usable build every week
- 04Store submission / production deploy
- 05Handover or ongoing maintenance
