TypeScript as a contract
Strict types, exact optionals, and defensive indexed access block ambiguity before the build.
BUILD FILE. 001 / SELF-DIAGNOSTIC
Aesthetics open the conversation. This dossier shows what lies underneath: rendering, budgets, degradation, security, and delivery contracts.
SYSTEM LENSES. 00 / PRODUCT → CODE
Product, systems architecture, and applied AI are angles on the same practice: turning a question into something that can be used and evaluated.
PRODUCT ENGINEERING / ACTIVE LENS
Code starts with the problem, crosses a complete vertical slice, and returns as a product signal.
hypothesis -> vertical_slice -> signal -> iterationOBSERVED SIGNAL07 products / mobile, operations, fintech, automation, and games
DELIVERY TRACE. 01 / REQUEST → EVIDENCE
The route delivers semantics and navigation before JavaScript. Motion and tools arrive as progressive enhancement through small boundaries.
Metadata, semantic content, and JSON-LD are born with the route and never depend on hydration.
Vinext and Vite resolve pages, styles, and modules before release; the sanitizer inspects the output.
CSS, JavaScript, and fonts receive immutable names; responsive media keeps explicit dimensions and its own cache.
Nine small islands add search, movement, and controls without taking ownership of the main content.
semantic route → sanitized build → immutable assets → bounded enhancementPERFORMANCE BUDGET. 02 / BOUNDED COMPLEXITY
Values measured in the latest local artifact. Limits live in code and fail verification when a change exceeds the agreement.

CLIENT ISLANDS. 03 / WHAT HYDRATES — AND WHY
Each island has a narrow responsibility and a path without JavaScript. The fallback is part of the design, not an error message.

| 02 | ParticleLogo | reactive particle mark | static, readable wordmark |

ADAPTIVE UI. 04 / THE ENVIRONMENT IS ALSO INPUT
System preferences change presentation and motion without requiring a separate menu. Information remains available in every mode.

The portfolio needs no camera, cookies, or third-party scripts. Response policies turn that absence into a verifiable boundary.
CSP keeps files on the same origin and blocks executable attributes; the runtime-required inline bootstrap remains a documented cost.
POLICY / ENFORCEDFrame ancestors, frame source, and X-Frame-Options prevent silent third-party embedding.
POLICY / ENFORCEDCamera, microphone, geolocation, payments, USB, and browsing topics remain disabled.
POLICY / ENFORCEDNo cookies, analytics, remote fonts, pixels, or background connections in the institutional portfolio.
POLICY / ENFORCEDKNOWN LIMIT / SCRIPT-SRC KEEPS UNSAFE-INLINE FOR THE RUNTIME BOOTSTRAP / SCRIPT-SRC-ATTR NONE
DECISION LEDGER. 06 / CONTEXT → CHOICE → COST
Four short ADRs record why the implementation took this path, what was left out, and which evidence keeps each choice honest.
The portfolio needed to combine long-form narrative, search discovery, and interactive tools without turning every page into a client application.
STATIC HTML / 09 ISLANDS / NO-JS FALLBACKSParticles and transitions help communicate a technology lab, but they can compete with reading, battery, CPU, and visitor preferences.
BOUNDED CANVAS / DPR CAP / ADAPTIVE MOTIONDense cases must progressively reveal detail without hiding content from keyboards, assistive technology, or non-hydrated environments.
NATIVE DISCLOSURE / SEMANTIC METER / KEYBOARD PATHRecruiters, readers, and crawlers need to verify authorship, projects, and quality, while an institutional portfolio does not need behavioral surveillance.

PASSCONTRACT BOARD. 08 / LATEST CUT
Strict types, exact optionals, and defensive indexed access block ambiguity before the build.
ESLint and JSX/ARIA rules fail on errors and warnings alike; accessibility is never postponed.
Audited information pairs pass WCAG AA, with dedicated adaptations for contrast and forced colors.
No analytics, cookie, remote font, or background connection enters the institutional experience.
Nine custom modules remain isolated and below the 28 KB budget; useful content arrives first.
Sitemap, JSON-LD, RSS, canonicals, and JSON Schema connect pages, cases, writing, authorship, and contract.
BUILD HISTORY. 09 / FOUR CUTS
A short release log for the interface itself. Each cut added a verifiable capability without erasing the decision that came before it.
Palette, Sora, flask, and laboratory language became a responsive editorial composition.
TOKENS / ICONS / STATIC ROUTESHome, Experiments, and Zero were separated; blog, sitemap, RSS, and structured data opened discovery.
MULTI-PAGE / SEO / WRITINGCases gained maps, trade-offs, traces, failures, and a printable recruiter briefing.
07 CASES / BRIEF / COMMANDSReal budgets, incident drills, machine-readable surfaces, and the build itself became inspectable.
