Project description:
"[Request Purpose/Background]
We are launching a new web service that extracts information from image and audio data and provides analysis results to users. I will develop the AI ​​logic that performs the data analysis and simulation that forms the core of the service. However, to make it easy for even non-technical users to operate, we would like to outsource the user interface and overall system framework construction, and are seeking proposals.

[Request Details]
We are looking for a web framework with the following features that can be used by users on the official LINE account.
After construction, we would like it to operate fully automatically without human intervention and with minimal running costs.
*The data analysis and simulation logic will be provided by me.

• Plan selection, application, and payment functions

• Implement a service description, application, and payment functionality (credit card/QR code payment) for the following three plans.

• Basic Plan: Reads information from image data and provides analysis results.

• Standard Plan: In addition to the Basic Plan, this plan also includes analysis using audio data or manually entered data.

• Premium Plan: In addition to the Standard Plan, this plan also provides simulation results for "what if" situations.

• Cancellations and refunds are not permitted for any reason after payment has been completed.

• Data Submission and Manual Editing Function

• After payment is completed, users will be able to submit data via image, audio, or manual input, depending on the plan they select.

• For audio data: We would like a system that automatically extracts audio segments related to specific events from long recordings and displays them to the user.

• Data Load Confirmation and Manual Editing: Please provide a function that displays the results read by the AI ​​to the user and allows them to manually edit them as needed.

• Please clearly remind users in the UI that manual edits are an important step that significantly improves analysis accuracy.

• Data cannot be resubmitted once it has been submitted.

• User Data Accumulation Function

• Please create a system that accumulates analysis data for each user and repeatedly analyzes the same user, allowing the AI ​​to provide more personalized and detailed analysis results.

• Final analysis and report display function

• After the user confirms their manual corrections, a final analysis is performed and the results are displayed as a report.

· After the system goes live, I would like to have a management screen with a dashboard-like interface, as well as easy-to-understand specifications and manuals, so that even I, who lacks IT skills, can continue to manage and maintain it.

[Desired Skills/Experience]
• Experience developing with LINE's LIFF (LINE Front-end Framework)
• Experience developing integrations with WebAPIs
• Experience integrating APIs with payment gateways (Stripe, Square, etc.) (credit card/QR payments)
• Ability to carefully explain things in easy-to-understand terms, even to clients without IT expertise
• Understanding of UI/UX (especially ways to clearly communicate the importance of manual corrections)
• Polite and smooth communication is preferred.

[Request for Technical Proposals]
We are considering building a service using Google Apps Script (GAS), which is simple and reduces running costs. However, depending on the request, it may be difficult to implement using GAS.
When making a proposal, it would be very helpful if you could let us know your opinion on whether it is feasible with GAS, and if that is not possible, alternatives such as Firebase or AWS, along with any additional costs or operational costs that may be involved." (client-provided description)
