SHOPIFY - CUSTOM CALCULATOR APP DEVELOPMENT

I am looking for a Shopify expert to develop a custom calculator module app for my online store. The purpose of the app is to calculate product prices based on specific criteria. The app does not need to be published into Shopify App Store but does need to be made able on my individual store.

The Shopify app that I am looking to have developed is front end and backend. The app is a custom calculator for an online interior decorating store. The calculator must comprise of the following modules: fabric, curtains, headboards, cushions, wallpaper, paint. There are meta fields and independent data tables which need to be used as reference point for the calculator.

Design:

Integration:
- The calculator will work independently and will not need to integrate with any other apps or systems.

Ideal Skills and Experience:
- Extensive experience with Shopify app development
- Strong proficiency in front-end development languages and frameworks
- Ability to create user-friendly and visually appealing interfaces
- Attention to detail and ability to accurately calculate prices based on given criteria
