An Excel import feature across seven repositories
Read the story
We needed an Excel upload feature for a list of accounts, with AI mapping the sheet’s columns to our model’s fields and storing the data. The work covered validations, five to six UI screens, notifications, asynchronous processing, and changes across seven repositories.
We estimated ten weeks of effort for one engineer. Right after the design and product grooming meetings, we used Shifu and GPT-6.1 Sol at high reasoning to produce the initial implementation in two hours. We then spent two more weeks reviewing, merging, testing and launching the changes produced by AI.
Ten weeks was the original effort estimate. Two hours describes the initial implementation, followed by two more weeks of review, integration, testing and launch.
