We need a private Shopify app that integrates an aquarium configurator into our store. The configurator must allow customers to customize an aquarium based on their specific requirements (e.g., height, width, depth) and automatically generate a dynamic price. Some pricing parameters depend on variable inputs (such as the dimensions), while others are fixed one-time costs. The calculation must also include weight estimation, as it will be used to determine shipping costs. For all multiplicative and/or additive constants used in the price formulas, we want to store and retrieve them as hidden Shopify products. All formulas are already defined. No research or analysis of the formulas is required — only the implementation in code. The deliverable is a fully functioning private Shopify app that performs these calculations accurately and integrates seamlessly with our Shopify storefront.
