# Code Architect

> Senior Next.js / React / TypeScript engineer

A senior Next.js, React and TypeScript engineer that implements production features, makes architecture decisions, and pays down technical debt. It writes type-safe code with tests first, then hardens performance and Core Web Vitals. Every fix starts by looking at the live page first, and no API route ships without its test written before the code.

## Use cases
- Building a production React/Next.js component from a design
- Writing API routes and server actions with tests
- Fixing Lighthouse and Core Web Vitals on a slow page
- Refactoring legacy code and resolving TypeScript errors
- Implementing a webhook or third-party integration

## Benefits
- Ship features that work the first time, not after three revision rounds
- Strict typing catches bugs before they reach production
- Faster pages that pass Core Web Vitals out of the box
- Clean, maintainable code your team can build on

## What’s included
- Next.js/React/TypeScript implementation with strict typing: no any/unknown shortcuts
- Pre-code verification habit: see the live page first, then write the fix
- API route discipline: auth → validation → authorization → logic, with tests first
- Component work with all four states handled: loading, error, empty, success
- Batch-commit and deploy hygiene: logical units, no WIP commits
- Performance fixes on the code side: bundle, hydration and render paths

## Who it’s for
Teams that need senior-level frontend implementation without hiring a senior engineer.

## How it runs
Writing a fix without seeing the page is blind surgery, and this agent refuses it. It loads the field lessons, opens the live page first, builds with tests and types, then proves the symptom is gone on the deployed URL.
1. Before touching client site code it reads the agency's web engineering standard, the customer's status line and any previous work record, so field lessons (like silent GA4 env trailing-newline death or base_tree commit catastrophes) are loaded before the first edit.
2. Sees the current behavior first: opens the live page with WebFetch or Playwright and confirms the reported symptom actually exists. Writing a fix without seeing the page is treated as blind surgery and refused.
3. Implements by type: UI components are built headless (Radix or shadcn plus Tailwind) on an 8pt grid with all four states (loading, error, empty, success); API routes are written test-first, the test fails RED, then Auth, Zod validation, Authorization, logic, rate limit, until GREEN.
4. Compiles with zero TypeScript errors and commits through base_tree-safe GitHub pushes, then polls the deployment until it is READY instead of waiting passively.
5. Verifies the specific symptom on the live URL, not just HTTP 200: if the fix was a dropdown opening upward, it checks the dropdown direction; if the layout was narrow, it measures the content width. Regression on previously working behavior is checked in the same pass.
6. Runs a 6-point quality bar (types, live proof, 4 states, no regression, architecture laws, security) and, whenever UI was produced, hands the result to the QA agent as a mandatory chain step before calling anything done.

## FAQ
### Is this only useful if I am on Next.js and React?
Yes, its depth is in the Next.js, React and TypeScript stack, including API routes and server actions. For a Vue or pure-backend project it is the wrong fit, not a generalist.

### Does it make real architecture calls or just emit code?
It is built to make implementation decisions and pay down technical debt, not only fill in a component. That includes restructuring a slow page to fix Core Web Vitals rather than patching the symptom.

### Will it own the whole feature end to end, including the design?
It implements from a design and writes the tests around the logic, but it works from a brief or spec you set. The product direction and the visual design come from elsewhere; it builds the thing well.
