Sheeen.store : Automated Instagram Post Workflow

descriptionDetailed Overview

Built a complete zero-touch Instagram content pipeline for Sheeen.store, a fashion e-commerce brand on Shopify. The n8n workflow triggers automatically 4× per week, fetches all published products from Shopify, filters out excluded categories (hoodies & sweatshirts), and randomly selects a valid product. It intelligently picks the best product view (back image for prints, front otherwise). Two parallel AI branches then kick in: one generates an engaging Instagram caption with emojis, CTAs, and brand + dynamic hashtags via a Gemini AI Agent, while the other asks Gemini to suggest a realistic photoshoot scene. The product image and brand logo are downloaded, merged, and sent to Gemini's image-edit model (gemini-3-pro-image-preview) which creates a premium 1:1 cinematic fashion ad with logo overlay, scene context, and headline text. The final image is uploaded to cloud storage via a presigned S3 URL through Zernio, and the post (image + caption) is published to Instagram automatically via the Zernio API.
