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.

Change-Intent Governance: The Missing Layer
IDPs govern what exists; agent gateways govern single tool calls. The layer between them — impact computed from immutable snapshots, decisions on an append-only ledger — is what AI-native delivery now requires.

I Said Closed Source Isn't a Moat. Here's What I Keep Closed Anyway.
The line between what to open-source and what to keep closed isn't about secrecy as a moat — build-time artifacts get more valuable by being public, while a runtime platform stays closed until switching-cost gravity, not hidden code, gives it real defensibility.

Closed Source Isn't a Moat. Here's the Filter I Actually Use.
Secrecy alone is a head start, not a moat; the real filter is whether an asset gets more or less valuable as the underlying model improves, which is what actually decides what's worth protecting.
