Shopify Developer Needed – Simple Dog Food Feeding Calculator (Install + Integrate)

I own a growing fresh dog food delivery business built on Shopify and need a developer to create and install a simple, clean feeding calculator on my website. The goal is to allow potential customers to enter basic information about their dog and instantly receive: Daily feeding amount (lbs/day and oz/day) Weekly amount (lbs/week) Approximate number of 1 lb containers needed per week This should be lightweight, fast, mobile-friendly, and integrated cleanly into my Shopify theme. Calculator Inputs The calculator should allow users to input: Dog’s weight (lbs) Goal: Maintain weight Lose weight Feeding formulas: Maintain weight = 2.5% of body weight per day Weight loss = 2.0% of body weight per day Outputs: Daily feeding amount (lbs + oz) Weekly amount (lbs/week) Containers per week (1 container = 1 lb) The calculator should display results dynamically without reloading the page. Technical Requirements Built directly into Shopify (no third-party quiz app) Clean, minimal UI that matches brand styling Mobile optimized Lightweight (no heavy scripts) Easy for me to edit later (clear code comments preferred) Installed on a dedicated page (e.g. /feeding-calculator) Deliverables Fully functioning calculator installed on Shopify Clean styling consistent with existing theme Brief Loom video walkthrough showing: How to edit percentages if needed Where the code lives Testing across desktop and mobile Apply tot his job Apply To this Job
