Chrome Extension for AI Music Production Tool (Suno Companion PRO)

Senior Chrome Extension Developer for AI Music Production Tool (Suno Companion PRO) Project Overview. I am looking for an experienced JavaScript developer to build Suno Companion PRO, a productivity-focused Chrome Extension for the [login to view URL] AI music platform. The extension is designed to bridge functional gaps in the current Suno UI, providing professional "DAW-like" features for power users. The core logic and architecture (Manifest V3) have been mapped out. I need a developer to implement the final code, ensure robust DOM injection, and handle client-side audio transcoding. Key Features to Develop: Precision Extend Sync: A hook into the site's element to capture live timestamps and auto-fill "Extend from" input fields. Structural Assistant: A UI toolbar injection that allows users to click-to-insert production tags ([Chorus], [Drop], etc.) into textareas. The Prompt Vault: Integration with [login to view URL] to save, manage, and copy previous prompt "DNA" (styles and lyrics). Batch Multi-Format Downloader: A system to scrape song metadata, rename files dynamically, and provide a client-side conversion from MP3 to WAV using the Web Audio API. Technical Stack: Manifest V3 (Mandatory) JavaScript (ES6+) with heavy use of MutationObserver and Message Passing. Web Audio API for audio buffer manipulation and WAV encoding. CSS3 for native-looking UI injection. Requirements: Proven experience with Chrome Extensions that interact with complex React-based Single Page Applications (SPAs). Understanding of DOM persistence (handling UI injection that doesn't break when the page navigates). Ability to write clean, minifiable code ready for Chrome Web Store submission. Deliverables: Complete source code folder (Manifest, Content Scripts, Background Service Worker, Popup). A "Production Build" (Minified version). Brief documentation on how to update DOM selectors if the target site changes its layout. Deadline: 4 days
