I am a product leader and design engineer. I moved closer to code so I could ship the whole loop myself, then measure what changed.
Product, Design & AIEngineer
I build product systems and leave the instruments behind to measure them. Since 2008.
What makes a product system worth trusting?
A machine now works at every stage of making a product. I build what it works inside: the criteria it reads, the system it draws from, the gate it cannot talk past.
- 01 · Research
Criteria
The machine reads the market; the criteria decide what counts.
- 02 · Spec
Acceptance
The machine drafts the spec; acceptance is what it can be held to.
- 03 · Design
System
The machine generates the screens; the system is why they come out on-system.
--ctl-36: 36px; --r-3: 8px; --dur-base: 200ms; - 04 · Build
Gate
The machine writes the code; the gate refuses what it cannot prove.
- routes gated
- errors, last run
- 05 · Measure
Registry
The machine reports the numbers; the registry makes each one carry its source.
- people reached
- daily active users
- lower operations cost
Until 2026, no title I ever held said engineer.
Read three cases in full
Each case carries its own measured numbers. They live inside the case, and every one of them resolves through the dedicated Evidence page, grouped by how it was measured.
Writing
Design system thôi chưa đủ: để suy luận và ra quyết định, AI cần thêm layer ontology
Design system có đủ tài liệu, rule cũng viết rõ, vậy sao Button trong code vẫn sai? Vì design system được viết cho người đọc, còn AI cần thêm một layer ontology để biết cái gì nối với cái gì, và vì sao.
Cắt người, xây máy chủ: AI thay người thật, hay chỉ là lý do được nêu?
Làn sóng sa thải công nghệ năm nay qua số liệu: ai cắt, cắt vì sao, và chữ AI trong lý do được nêu nói lên điều gì.

What I hold to
The work is not the screen. The work is the change it creates.
On outcomes A claim ships with its evidence in the same viewport, or it does not ship.
On evidence Every number here resolves to how it was measured, or it is not a number.
