This certificate was awarded to Ong Chuu Harn on 18 September 2026 for completing Mission 6, Build a Smart Home Security Dashboard, at Sigmaschool.
What that means: “I can build a protected React application with routed pages, shared authentication state, route guards, and conditional device status interfaces.”
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.
