Built a high-performance Visual AI Workflow Builder(Weavi.ai clone), enabling users to orchestrate multi-modal LLM workflows using an intuitive drag-and-drop infinite canvas. The platform integrates Google Gemini for AI processing, Trigger.dev for serverless background execution, and PostgreSQL for workflow/run persistence. Designed with strict separation of concerns, real-time execution feedback, and production-grade architecture. Key Modules:

• Infinite canvas workflow builder (React Flow) with mini-map & zoom controls
• 6 node types: Text, Image Upload, Video Upload, LLM (Gemini), Crop Image, Extract Frame
• Clerk-based authentication with protected user workspaces
• Serverless execution engine with parallel DAG processing (Trigger.dev)
