Title: Chrome Extension + Web Uploader for Structured Form Autofill (MV3 + Firebase) One-liner: Build a Manifest V3 Chrome extension that autofills complex web forms from a JSON payload, plus a lightweight web uploader that turns PDFs/images into structured JSON using OCR. Secure, resilient, and easy for operators. Scope: 1) MV3 Chrome Extension - Autofill engine for text/email/number/date/select/radio/checkbox. - Resilient to SPAs/iframes (MutationObserver, retries, proper events). - Mapping system with an Options page editor & test-fill mode. - Background service worker: fetch short-lived signed URL to JSON from Firebase Storage (no PII persisted). - Diagnostics overlay: show filled/unfilled fields and reasons. 2) Web Uploader (React Website) - Drag-drop PDFs/images → uploads to Firebase Storage (resumable). - Firestore batch doc; live status. - Cloud Function runs OCR → normalized JSON + validators (DOB→age, Aadhaar/mobiles length, % bounds). 3) Ops/Docs - README with setup/deploy steps. - Playwright tests on mock form page proving autofill works. - Least-privilege permissions; host whitelist; privacy policy draft. Reuse vs Build: Take from GitHub: - MV3 boilerplate (service worker + content script + options page). - Firebase examples for Storage/Firestore/Functions. - Google Vision SDK usage samples; optional Tesseract/PaddleOCR samples. - Playwright test scaffolds. Must be custom: - Normalized JSON schema (identity, contact, academics fields). - Validators + flags. - Fill Engine resilience (SPAs, iframes, date pickers). - Site adapter interface (per-site mapping, hooks, versioning & kill switch). - Diagnostics overlay. - Signed-URL flow (service worker). Acceptance Tests: - On a mock form page, extension fills: text, email, number, date, select, radio, checkbox, iframe field. Diagnostics show green/amber. - Options page: DOM picker suggests selector → saves mapping → test-fill works. - Web uploader: upload PDFs → Firestore shows queued→processing→completed; Storage has JSON; validators flag issues. Milestones: M1 (20%) MV3 skeleton + basic fill + README. M2 (30%) Advanced widgets + SPA/iframe handling + diagnostics + Playwright tests. M3 (30%) Options editor + remote mappings (Firestore) + signed-URL flow. M4 (20%) Web uploader + OCR Function + validators + end-to-end demo. Ownership: Work-for-hire, IP assignment to client. NDA required before any private site details. Tech Stack: - Extension: MV3, JavaScript/TypeScript, [login to view URL], content scripts, service worker. - Web: Plain HTML+JS (or Vite minimal) + Firebase Web SDK. - Backend: Firebase Functions (Node.js), Firestore, Storage, Google Vision API. - Tests: Playwright.
