AI Video SaaS Development

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). Show More
