I need an experienced Chrome-extension developer to create a minimum-viable product that embeds directly into Etsy’s listing editor and uses an AI back-end (OpenAI, Claude or similar) to improve everything a seller writes. Inside the Etsy interface the user should be able to click an “Optimise” button and instantly receive rewritten titles and descriptions, refreshed keyword/tag suggestions and data-driven price guidance. All processing can run through a cloud function you set up; the extension simply calls the endpoint and presents the results without refreshing the seller’s page. Because this will launch as a freemium product, the code has to include: • A subscription gate that unlocks premium suggestions once the daily free quota is reached (Stripe, Lemon Squeezy or Paddle are all fine—pick the one you’re fastest with). • Plan management and metering handled server-side so quota limits cannot be bypassed. • Chrome Web Store-ready packaging (Manifest V3, review-friendly permissions, icons, screenshots). Clean architecture matters to me. Use TypeScript, React (or Svelte) and keep everything linted, documented and containerised for simple hand-off. The back-end can be Node/Express or Cloud Functions; just make sure it scales. Acceptance criteria 1. One-click optimisation works for titles, descriptions, tags and price. 2. Freemium limits trigger correctly and premium upgrades unlock instantly. 3. Extension installs from the Chrome Web Store with no warnings and runs smoothly on the latest Chrome for Windows and macOS. 4. Codebase passes an end-to-end test suite I can run with one command. Let me know your preferred AI provider, payment stack and any questions about Etsy’s DOM quirks, and include a link to at least one production Chrome extension you’ve shipped.

Hi there, I’ve read your Etsy Listing Optimizer extension brief and I’m confident I can deliver a clean, scalable MVP that drops right into Etsy’s listing editor. I will build a MV3 Chrome extension (TypeScript + React or Svelte) with a one-click “Optimise” button that calls a cloud function endpoint to rewrite titles and descriptions, refresh keywords/tags, and provide data-driven price guidance, all without refreshing the Etsy page. The backend will be Node/Express or Cloud Functions, containerised, and will handle plan mgmt and metering server-side so quotas can’t be bypassed. I’ll implement a freemium gate (Stripe, Lemon Squeezy or Paddle), with per-day free quotas and instant premium unlocks on upgrade. The codebase will be clean, tested, and shipping-ready for Chrome Web Store packaging (Manifest MV3, review-friendly permissions, icons and screenshots). I’m targeting a 28-day timeline for a solid MVP, plus a one-command end-to-end test script and thorough docs for hand-off. If you’re happy, I’ll start with a quick design review and share a concrete stack plan. Which AI provider and pricing model do you want to start with (e.g., OpenAI or Claude), and are there any data residency or privacy constraints I should follow? Best regards,

Hello [ClientFirstName], I’ve read your Etsy AI Listing Optimizer Extension brief and I’m confident I can ship a robust MVP that feels native to Etsy’s editor while delivering scalable AI-driven optimization. I will build a TypeScript + React-based Chrome extension (Manifest V3) that communicates with a serverless backend (Node.js) to handle AI processing, pricing guidance, and subscription metering on the server-side, ensuring quotas can’t be bypassed. What I’ll deliver: a one-click Optimise button inside Etsy’s listing editor that rewrites titles and descriptions, refreshes keyword/tag suggestions, and provides data-driven price guidance. A freemium tier with a server-validated quota using Stripe/Lemon Squeezy/Paddle, a secure plan management API, and a responsive Chrome Web Store packaging workflow (icons, screenshots, permissions, and automated linting/documentation). I will use a scalable architecture with containerised services and a clean codebase, so hand-off to your team is straightforward. Preferred AI provider: OpenAI (with contingencies for Claude or other providers). Payment stack: Stripe for fast, reliable onboarding. I will address Etsy DOM quirks and provide one production Chrome extension as a reference, plus 2-3 relevant project links below for portfolio credibility. Next steps: I can start with a 2-week MVP sprint, deliver a working prototype for internal testing, and then finalize the Chrome Web Store packaging and end-to-end tests. Best regards,

Hi there Employer, Thank you for sharing such a well-articulated project brief. I’m excited by the opportunity to build an AI-powered Chrome extension tailored to Etsy sellers, as described. Your focus on clean architecture, seamless integration, and user experience aligns closely with my development philosophy. I have extensive experience developing production-ready Chrome extensions using TypeScript and Svelte, with a strong emphasis on clean, maintainable code and robust testing. Notably, I recently delivered a Chrome extension (see: [link to extension]) that embedded directly into a third-party dashboard, leveraged OpenAI’s API for content recommendations, and included Stripe-based subscription gating—very similar in scope to your requirements. My background in both Node.js/Express cloud backends and Chrome extension best practices ensures end-to-end delivery with smooth handoff and documentation. For your solution, I recommend OpenAI’s GPT-4 Turbo for high-quality, scalable optimizations, and Stripe for subscription management given its maturity and developer tooling. The extension will interact with Etsy’s DOM using Svelte components for lightweight UI overlays, and all AI processing will be securely handled server-side via cloud functions. Freemium quotas and plan management will be enforced server-side, and the extension will be packaged for Manifest V3 compliance, ensuring a smooth Chrome Web Store review process. I am happy to discuss Etsy’s DOM quirks or specifics around quota metering. Please let me know if you’d like to see a demo of relevant work or have any questions about the technical stack. Thanks and Regards

Hi I can develop your Chrome extension MVP using TypeScript + React with a clean MV3 architecture, embedding directly into Etsy’s listing editor to deliver AI-powered optimization for titles, descriptions, tags, and pricing. The main technical challenge is interacting reliably with Etsy’s dynamic DOM while processing content off-page, and I solve this with stable selectors, shadow-isolated UI elements, and a scalable Node/Cloud Function backend for AI generation. I’ll implement a secure freemium system with server-side metering, quota enforcement, and instant premium unlocks via Stripe or Lemon Squeezy. The extension will be packaged for the Chrome Web Store with minimal permissions, documented code, and a full end-to-end test suite. I’ve shipped production MV3 extensions before and focus on maintainable, linted, containerised codebases. Thanks, Hercules

Hello, I recently built a Chrome extension that injects AI writing tools directly into a third-party web editor, using TypeScript + React, a Node/Express API, and Stripe subscriptions with server-side metering. It handled inline DOM injection, one-click content rewriting, quota enforcement, and Manifest V3 compliance. For your Etsy extension, I will embed an Optimise button inside the listing editor, connect to your chosen AI provider (OpenAI or Claude), and return improved titles, descriptions, tags, and price guidance without page refresh. I’ll implement server-side quota tracking, Stripe-based freemium gating, and instant unlock on upgrade. The codebase will be fully typed, linted, containerised, and packaged Chrome Web Store–ready, with an end-to-end test suite and clean architecture. I can start your project immediately and am committed to delivering the highest quality and fastest possible turnaround. Best regards, Elenilson
