01 · BRIEF · CASE 01 OF 05

I built this portfolio with AI, and kept the decisions human.

Six weeks with Cursor, Claude, and Vercel, documenting how human taste still sets the ceiling when AI raises the floor.

A production-grade portfolio, two reusable workflows, and one clear boundary between AI generation and human judgment.

03 · METHOD · CENTAUR, NOT CYBORG

Human in the saddle. Always.

Ethan Mollick's framework draws a line between Centaurs and Cyborgs. A Centaur divides tasks with AI and keeps steering. A Cyborg fuses with it completely.

I'm a Centaur. The structure of every page, the positioning decisions, the copy that sounds like me — those were mine. AI produced faster drafts, better variations, sharper critique than I could generate alone. The decisions were mine.

AI GENERATEDREF · 03-A

"Matt Stangl is a strategic design leader who transforms complex enterprise challenges into measurable business outcomes through human-centered methodologies and systems thinking."

SOURCE · LLM DRAFT · COMPREHENSIVE PRESET

I CHANGED IT TOREF · 03-B

"I rebuild fragmented enterprise experience as one operating model that actually ships."

SOURCE · MATT · POSITIONING PASS · 04/12

WHY · CAPTIONThe AI version is a job description. Mine is a positioning statement. AI defaults to comprehensiveness; I default to specificity. That pattern repeated across every piece of copy on this site.

The hardest version of this lesson came in week four. I let AI write three case study pages end to end. The output was fluent, professional, and completely generic — the same portfolio language on a hundred other sites. I tore it down and rebuilt from what actually happened: the real pivots, the real numbers. That version is what you're reading now.

Three artifacts. Three interactions.

A service record is what a mechanic logs when work is done — what changed, who did it, when, and why. Tap, drag, tap.

Design Review Terminal

Two critique passes, thirteen findings — tap a pill to narrow the log.

CLICK PILLS TO FILTER

~/critique · v2 · post-desktop
F·01CRIHero scatter dominates the page; impact metrics buried below fold. → promoted Impact Console above scatter (W4).
F·02REVWanted to remove fiche grammar as "too dense." Reversed: density is the differentiator. Doubled down instead.
F·03MAJCase study sections didn't earn their length; reading dropped at section 03. → cut three sections, restructured to 6.
F·04MAJTone in About slipped to corporate. → rewrote in first person, motorcycle metaphor stayed.
F·05CRIMobile nav broke at 480px; CTA collided with brand. → collapsed to icon menu under 880px.
F·06MAJColor contrast on .ink-3 below WCAG AA on dim callouts. → darkened var(--ink-3) by 6%.
F·07MINFIG stamp positioning drifted between hero and ledger. → standardized to absolute · top:1rem · right:1rem.
F·08REVAI suggested removing the section dimension callouts. Reversed: they're the page rhythm. Kept all five.
F·09MAJCrosshair fade timing felt mechanical. → added 400ms transition-delay after IO trigger.
F·10CRIImpact Console tabs not keyboard accessible. → added arrow-key + roving tabindex.
F·11REVWeekly build log felt redundant next to Build Telemetry. Reversed: vertical log, different scale from Build Telemetry.
F·12MINSheet footer cells wrapped at 720px on Safari. → explicit grid-template-columns + media query.
F·13MINInter-Italic loaded 600 weight unused. → trimmed to 400/500/600 regular only.

Each finding is a real critique I made of my own work, with the decision and reversal logged. Reversals are when AI was right and I was wrong, or vice versa.

05 · SERVICE BULLETIN · WHAT I GOT WRONG

I skipped the brief twice. I paid for it twice.

I skipped the brief twice. Both times the failure mode was the same: asking for output without specifying what mattered most.

REF · 05-AONCE · IMPACT DASHBOARD

Asked Cursor to "design the impact dashboard."

No hierarchy, no metric priority, no interaction logic. Output was technically correct and visually incoherent — every element equally weighted because I hadn't said what mattered most. Two hours fixing what a 15-minute brief would have prevented.

REF · 05-BTWICE · CASE STUDIES

Let AI write three case studies end to end.

Same root cause. Same generic result. The fix was never less AI. It was more specificity. The version you're reading is the rebuild.
