Context
Our client, a North American entrepreneur, identified a trust gap in online purchasing: buyers often had to rely on fragmented, inconsistent, or unreliable feedback sources when evaluating sellers. The goal was to build an online reputation platform that would aggregate customer reviews, improve reputation transparency, and help users make safer purchase decisions at scale.
Challenges Solved

- Fragmented and unreliable reviews — buyers lacked a single, trusted place to assess seller reputation.
- Fraud risk in online purchasing — the platform needed to make reputation signals more visible and easier to evaluate.
- Large volumes of user-generated content — review data had to be structured, indexed, and searchable without slowing down the user experience.
- Fast user base growth and rising data load — the platform needed an architecture prepared for scale from the start.
Why this project was complex

- The platform had to process and structure large volumes of user-generated review content.
- Search and review indexing needed to stay fast as review data and user activity grew.
- The product had to support both buyers and businesses within one multi-role platform workflow.
- Reputation data had to be presented clearly enough to support quick trust-based decisions.
- The system needed scalable infrastructure ready for increasing load.

Our customer came up with the ideas for the platform's initial designs, but wanted to improve user experience and user navigation. The redesign focused on improving information clarity, trust perception, and speed of decision-making.
Key principles:
- easier review and rating background checks
