Budget: 2220 UAH Deadline: 3 days
Ready to implement this as an HTTP service on Node.js. The server will accept parameters from the URL, dynamically insert them into the image template, and deliver the finished photo on the fly. For image generation, I will use canvas or sharp; for the second image — generating a barcode (Code128 or PDF417) using bwip-js and inserting it into the template. Two endpoints can be created (front/back) or switching by parameter. The solution works without saving files, is fast and scalable; if necessary, I will add parameter validation and caching. The implementation time is 2-3 working days with testing.
