Problem

The client relied on fragmented tools for sales, lead handling, and course operations. They needed a single platform to improve conversion, manage affiliates, and deliver a personalized onboarding experience.

Solution

I built a full-stack platform combining course checkout, affiliate management, and a trading-character assessment that segments users and personalizes their next steps.
