Shopify Developer Needed – Automatic Social Preview Images for Deal Website

I run a Shopify-based deals website that posts Amazon, Walmart, and other online deals. I am looking for a developer to build an automatic system that generates custom social sharing images and link previews for my deals. Currently, when I share a deal link on WhatsApp, Telegram, Facebook, X, etc., it only shows the basic product image. I want the shared link preview to automatically display a professional branded deal image instead. Requirements: Automatically generate a custom image when a product is published Automatically use that image as the social sharing/Open Graph image Work on WhatsApp, Telegram, Facebook, X, and other social platforms Pull information directly from Shopify Include my logo Require no manual work for normal deals Price-Based Deal Mode The image should automatically display: Product image Sale price (must show the exact Shopify sale price) Regular price Percent off Product title Store logo (Amazon, Walmart, etc.) For the regular price only: Automatically round to the nearest whole dollar Example: $29.99 → $30 Example: $219.99 → $220 Custom Promotion Mode I also want the ability to create custom promotional images that do not use pricing. Instead of prices, I should be able to enter: Custom headline Custom subheadline Custom badge text Examples: Limited Time Offer Prime Day Deals Amazon Haul Clearance Best Deals This Week Product Controls For each product, I need the ability to: Enable or disable the custom image system Switch between Deal Mode and Custom Promotion Mode Enter custom headline text Enter custom subheadline text Enter custom badge text Override any automatically generated text if needed VERY IMPORTANT I want the lowest possible ongoing cost. My preferences are: No monthly fee One-time setup cost Self-hosted solution if possible Avoid paid third-party services unless absolutely necessary When applying, please explain: How you would build this Whether there are any monthly fees If there are fees, exactly how much Whether this can be done without Canva or other paid services Estimated setup time Examples of similar work you have completed To show that you read the entire project, please start your proposal with: DEAL IMAGE PROJECT
