What needed solving

A small café competing during COVID-19 needed to maximize efficiency, customer satisfaction, and revenue without increasing headcount — every second of service time and every add-on sale mattered.

01research & customer insights

research & customer insights

Great café UX isn't just the menu — it's every touchpoint from order to pickup.

  • Used Power BI to analyze order trends, peak hours, and product mix performance.
  • Identified bottlenecks in prep workflows, shift scheduling, and inventory restocking.
  • Mapped the customer journey from menu browsing to add-on suggestions and repeat visits.
02design process

  • Ran A/B tests on add-on UI/UX enhancements using HTML, Python, and JavaScript — boosting conversion by 18%.
  • Designed prep workflow systems and shift scheduling tools for an 8-person team.
  • Built automated inventory restocking alerts to prevent stockouts during peak hours.
  • Integrated real-time feedback loops to adapt menu offerings quickly during COVID-19 constraints.
03design strategy

design strategy

Treat the café like a product — every workflow is a user flow, every menu change is an A/B test.
  • Applied product thinking to physical service — measure, iterate, and optimize like a digital product.
  • Used data to drive menu decisions rather than intuition — Power BI dashboards for daily operations.
  • Designed add-on prompts and upsell touchpoints based on customer segmentation insights.
  • Streamlined team operations with clear prep workflows, reducing chaos during rush hours.
