Context

The official portal for a metropolitan-government childcare support agency — a public-sector site where residents find care services and education providers, and where the center's own staff publish content. A separate PM owned the backend; I owned the entire front-end.

Problem

The client's requirements were scattered across spreadsheets, HWP documents and slide decks, and some of them contradicted each other. Building straight from those documents guarantees a 'this isn't what we asked for' conversation at delivery.

Decisions

Nothing got finalised in the UI before it was reconciled with the source documents

Any task that needed checking against the client's original xlsx, pptx or hwpx files had to record the reconciliation in the changelog instead of proceeding on assumption. Locking something in on the front-end first is the most expensive thing to undo.

Two concept directions, each in desktop and mobile

Public-sector projects have several decision makers. One concept invites unlimited revisions; two concepts force a choice. Presenting the mobile layout alongside the desktop one prevented the structure from collapsing on small screens after approval.

Gave the AI agents a rulebook before giving them the codebase

To gain speed from AI assistance without losing quality, I put an explicit working-rules document (CLAUDE.md / AGENTS.md) at the project root covering naming, CSS variables, responsive breakpoints and prohibited patterns — including the rule that when the docs and the code disagree, the code wins and the docs get corrected.

Carry delivery through to ongoing operation

I produced 76-page user and 52-page admin manuals from 60 user screens and 48 admin screens, with regeneration tools. Follow-up work covered text-size controls, search and sharing metadata, editor formatting and Korean font fallbacks.

What I owned

  • UI design (desktop + mobile)
  • Markup
  • The entire front-end
  • Front-end working standards
  • Project documentation

Actual deliverables

  • Homepage concepts A and B — desktop and mobile
  • Complete front-end implementation
  • Front-end working-rules document (CLAUDE.md / AGENTS.md)
  • 76-page user manual, 52-page admin manual and regeneration tools

Scope and verification

128 pages of user/admin manuals and ongoing improvements

The backend and the PM role weren't mine. I didn't get automated tests onto this front-end and QA was manual — I am adding test coverage on EXITO Seller, which is in progress now.
