Mission 4: Build an Activity Discovery Dashboard

Leonard Leong Sud Yen's Mission 4: Build an Activity Discovery Dashboard certificate

This certificate was awarded to Leonard Leong Sud Yen on 11 September 2026 for completing Mission 4, Build an Activity Discovery Dashboard, at Sigmaschool.

What that means: “I can build a login flow, fetch data from a real API, and turn JSON responses into a live, interactive page.”

Sigmaschool is a mastery-based programme where students build real, working software instead of watching lectures. Every mission is shipped to a live URL, walked through on video, and marked by a human instructor before it counts, so a certificate here means the work was seen and defended, not just finished.
