Job Title Full-Stack AI Developer: Build Credit-Based Video SaaS (n8n + Drag-and-Drop Editor + Multi-Currency) Job Description We are building a High-End AI Video SaaS (Credit-Based) for long-form content (up to 15 mins). We need an expert to develop a web-based dashboard where users can generate AI video clips and then refine them using a drag-and-drop timeline editor. The Core Workflow AI Generation: Users enter a prompt. The backend (n8n + fal.ai) generates a script (Grok 4.20), images (Z-Image), voiceover (Google Chirp 3), and video clips (Wan 2.1). The Editor: The generated clips are loaded into a timeline. Drag & Drop: Users can reorder clips (e.g., move clip #10 to position #3). Refinement: Users can edit the text/voiceover, "Regenerate" a specific clip, or upload their own video from their gallery/device. Credit System: Credits are deducted based on video length and quality. Technical Requirements Backend: n8n for workflow orchestration. AI Stack: fal.ai (serverless GPU) for Wan 2.1, Z-Image, and FlashVSR (upscaling). Frontend: WordPress or a React-based dashboard. Note: You must integrate a lightweight video editing SDK (like Creatomate, Shotstack, or a custom Canvas-based timeline) to handle the drag-and-drop UI and final FFmpeg rendering. Payments (Dual-Currency): * India: Razorpay integration supporting INR, UPI, and Domestic Debit/Credit cards. Global: Stripe integration supporting USD and International Credit Cards. Budget & Deliverables Budget: $2,500 (Fixed Price for MVP). Deliverable 1: Working AI orchestration (n8n + fal.ai). Deliverable 2: Dashboard with a functional drag-and-drop timeline and upload feature. Deliverable 3: Credit system synced with Razorpay (INR) and Stripe (USD).
