I personally developed a web app that allows groups to collectively give retirement gifts and birthday presents. It's a complete process from product voting → PayPay collection → Rakuten purchase, all without registration required and completed with just one URL.

【Background of Creation】
When I was in charge of organizing a gift for a farewell party at work, I experienced:
・Opinions on what to buy couldn't be unified via LINE
・It was difficult to manage who paid for what on my own
・I felt awkward asking people to pay me back, so I ended up covering the costs myself
From this experience, I thought "I want a tool that handles everything."
【Main Features】
・Search for products from Rakuten Marketplace and register candidates (up to 3 items)
・Everyone votes via URL and the decision is made by majority vote
・Collect payments via PayPay and share payment status in real-time
・After collection is complete, purchase directly from Rakuten
【Technology】
Flutter Web + Firebase
Rakuten Product Search API (via Firebase Functions)
