Case Study

Waferlee, a Community-Powered Deals Platform

A discovery platform where the community submits and votes on deals and coupons, with a custom 'Temperature' algorithm surfacing what is genuinely trending — plus the moderation and anti-abuse layer a voting product needs.

Waferlee, a Community-Powered Deals Platform

The Challenge

A deals site ranked by raw votes gets gamed on day one. The ranking needed to reflect momentum, not just totals — and every community feature (submission, voting, comments) invites abuse, so moderation and bot protection had to be part of the core design, not patches.

  • Trending must reflect momentum, not raw vote counts
  • Community submissions need a moderation pipeline
  • Voting invites bots and manipulation
  • Users expect to be notified when deals move

The Approach

I built a robust voting engine with a custom 'Temperature' algorithm that weighs votes over time, so fresh momentum beats stale totals. RBAC separates members from moderators, Google ReCAPTCHA guards the interaction points, and automated email flows plus multi-channel notifications keep the community engaged.

  • Custom 'Temperature' trending algorithm
  • Real-time voting, submissions and moderation
  • RBAC plus Google ReCAPTCHA against abuse
  • Automated email flows and multi-channel notifications

What I Built

A complete community product: contribution, ranking, moderation and engagement.

  • Robust voting engine with momentum-based ranking
  • Deal submission and moderation workflows
  • Secure interactions with RBAC and ReCAPTCHA
  • Notification and email engagement flows

The Outcome

Waferlee is live at waferlee.ae — a community platform where the ranking stays honest because the algorithm, moderation and anti-abuse were designed together.

  • Live at waferlee.ae
  • Trending feed driven by the Temperature algorithm
  • Community contribution with protected integrity
