PWA App Platform

It started as a project to improve the conversion rate for application forms when purchasing services or products. In order to reduce customer abandonment, a system was introduced to reduce the burden on the customer by remembering what the customer has entered in the form and automatically restoring past entries when the customer revisits the site, as well as by capturing camera photos and transcribing the text. Technically, the policy was to achieve a completely pay-as-you-go system by utilizing AWS to achieve a serverless architecture, and all processes were built using AWS Lambda. For the development language, TypeScript was introduced to unify the front-end and back-end development languages. For the front-end, React was introduced to realize PWA, and for the back-end, Express was introduced to improve productivity. After careful consideration, we decided to use Google Vision API only for the image loading part. Although we were able to achieve certain results in terms of reducing abandonment rates and improving UX, the project made us keenly aware of the need to work on daily improvements without being satisfied with the status quo, as general consumers' expectations for UX are increasing every day.
