Project Summary

Yellow provided UI design and development support to a sports-technology startup, producing wireframes, Figma mock-ups, and Flutter-based application builds. The team delivered multiple prototypes and a code repository, provided weekly progress reports, and remained on time and within budget while prioritizing end-user understanding.

Key Challenges

  • Build a proof of concept quickly to gather market feedback
  • Avoid disrupting the existing product lineup or shifting internal focus
  • Compensate for a relatively small internal team with limited time

Project Deliverables

  • Wireframes
  • UI designs and workable mock-ups
  • Multiple app versions/prototypes
  • Code repository

Project Solution

Yellow interviewed stakeholders to understand end users and then designed and built an application using Figma for UI/UX and Flutter for development. They produced wireframes, UI mock-ups, multiple versions of the app, workable prototypes for market feedback, and maintained a code repository while managing the project with weekly check-ins.

Project Outcome

  • Delivered near-final designs on the first attempt, minimizing the need for rewrites
  • Submitted deliverables on time and within budget with regular weekly check-ins
  • Produced multiple workable prototypes and a code repository for market testing
