Chrome Extension Developer – Amazon Seller Profit Calculator (MVP)

I'm building a Chrome extension for Amazon sellers. This is Phase 1 (MVP) of a larger project. Phase 1 scope: - Chrome extension (Manifest V3) that adds a side panel on Amazon product pages - Profit calculator: cost input, referral fee, FBA fee, net profit, ROI, break-even price - Show product data (price, sales rank) - Simple settings page (marketplace, default fees) - Clean, fast UI Requirements: - Experience building Chrome extensions (please send links) - JavaScript/TypeScript, React - Amazon SP-API experience is a big plus - 100% original code; I own all code and need GitHub access - Milestone payments, weekly updates, short demo at the end If Phase 1 goes well, I plan to continue with the same developer for Phase 2 (restriction checker, login, Stripe subscriptions). To apply, please send: 1. Links to Chrome extensions or Amazon tools you've built 2. Your timeline for Phase 1 3. Your experience with Amazon SP-API
