I would like to hire a Shopify Developer

Looking for a Ruby on rail (liquid) - Shopify expert with some experiences to develop 2 main customization on an existing Shopify template. I'm working on a Shopify store ([login to view URL] - not online yet) to sell some eco-responsible activities gift box presents. The user flow is that a user buy a gift box for a friend or family (let's call them the beneficiary) and the beneficiary will used a gift card to select a partner (in a list of around 15 partners) to book their eco-responsible activities. I have already set-up the store and user flow but I would need some help for an expert in order to : 1. Create a personalized form to ask the beneficiary to validate their gift card with some personal information. Each time a user will buy a gift box then they will obtain a gift card with unique ID that need to be validate by the user and/or beneficiary to activate the gift box. Please see an example here - [login to view URL] 2. Create an access for our partner to enter the information about the unique ID-gift card when a beneficiary will order the activity with the gift card and then give to the partner prior to the activity. I was thinking using to use a marketplace app but I don't need all those features and need to be simple for our partners. I was also thinking to use like a Excel Spreadsheet though G-suit to give the ability to each partner to enter their gift card number. Then with the same account staff access (with limited view) to all partners, they will be able to update the Excel spreadsheet.
