The necessary specifications for PCs and smartphones vary greatly depending on the situation.

• When special performance is required for specialized uses
• When you want the device to operate smoothly at all times
• When cost is a priority, even if there is some stress in operation
• When the device only needs to operate at a bare minimum, even with a cracked screen or degraded battery, and the lowest possible price is preferred

Especially when the latest specs are not required, a major challenge is that while old and slow devices are acceptable, it's unclear how "slow" they actually are.

Therefore, wouldn't it be convenient if we could help users purchase the most economical product by presenting them with devices similar to those they've used in the past and found to be "good enough"?

Required Features

• EC sales screen for devices procured by our company
• Input screen for models that consumers feel are "still good enough" (on the EC sales screen)
• Screen for administrators to input settings (on the EC management screen)
• Bot to create a DB referencing our own EC and other companies' websites
• Backend to compare user input with the DB and create an optimal list
• Part (frontend) to display the created list on the EC side
• App (Shopify app) to load the part and display it on the EC

Anticipated Technologies

• Sales Platform: Shopify
• Platform System: Liquid
• Frontend: Vue.js
• Backend: Ruby on Rails
• Server: AWS Fargate + Amazon DynamoDB + CloudFront
