Trading Cards Grading

PROJECT

For one of the largest German trading card shops, we have developed a sales website and mobile-first app, which digitizes the entire evaluation process (grading) for trading cards, from purchase and shipping to verification and labelling.

CHALLENGE

The object was a positive user experience while selecting cards for evaluation, as well as the maximum of possible support for the employees while doing the grading:

A web-based app connected to Shopify had to be built as a data-driven assistant to submit trading card informations
A huge amount of trading card data from multiple Google Sheets had to be transferd and continuously updated
A shop was needed to sell the grading-service to users
Based on his identification, the customer should be able to specify and finalize the order on a submission page
orders should be transact by employees asap, supported by QR code
It´s important during the entire process: there could be highly professional users as well as users without any prior knowledge – and both have to handle it

RESULT

In a team of frontend and backend developers, we implemented the ordering and grading process in two separate apps in web app, mobile-first app and database:

Automated import process from Google Spreadsheets into an expandable and dynamic database
Integration with Shopify web hooks for data transfer and extension
UX-optimized Single Page Application (SPA) to enter usefull data into grading process
Central database between OrderKit and GradingApp, also to search POIs
Communication between OrderKit and GradingApp using QR codes
State machine based grading process with pre/post conditions and user rights management
Export to Excel/CSV files for automated card labelling
Zero downtime deployments
Continuous deployment from Bitbucket pipelines
Infinitely scalable serverless architecture
