what I did

1. 01AI led the product idea and user-flow design, focusing on how to turn checkout into a reflective decision point by showing budget impact, savings-goal delay, and lower-cost alternatives.
2. 02AI worked on backend and product logic using FastAPI, MongoDB, and Gemini API to support personalized recommendations and behavior-aware decision support.
3. 03AThe most important design challenge was making the intervention feel helpful, timely, and non-intrusive within a real shopping workflow.
