This certificate was awarded to Ong Chuu Harn on 3 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.
