Close resume–JD keyword gaps and export ATS-safe docs

01 Hook

Applicants lose interviews to keyword mismatches — not to weak experience.

02 Context

Next.js product with import, builder, job scan, optimize, tracker, and pricing surfaces — Gemini parse optional via env.

03 Problem

Generic resume tools either phone home with data or dump advice without an editable optimize loop and ATS-safe export.

04 Insight

Local-first + accept/skip keyword closes beats a black-box rewrite — the user keeps ownership of every change.

05 Exploration

Wired scan → optimize → export, application tracker, unit tests (Vitest), Playwright smoke/workflow, Vercel-ready release check.

06 Decision

Kept the core local-first; LLM providers optional in Settings so the product works without locking users to one API.

07 Solution

Shipped Resume Helper v1.0: full site map from import through tracker, with health endpoint and production docs.

08 Impact

Proof of work: public repo with release:check (typecheck + tests + build) and end-to-end workflow coverage.
