Overview

Key Challenges

Rewardify needed an entire platform built in 10 weeks, including a Slack app, admin dashboard, and marketing site, while meeting strict Slack approval requirements and security standards.

Our Solution

We engineered a fully integrated ecosystem: a secure Slack app using OAuth 2.0 and Slack SDK, a scalable MERN dashboard, and a high-performance WordPress marketing site. The solution was delivered in 10 weeks with 92% code coverage and Slack Marketplace approval.
