Ong Chuu Harn's Mission 10: Build a Running Community App certificate
This certificate was awarded to Ong Chuu Harn on 19 October 2026 for completing Mission 10, Build a Running Community App, at Sigmaschool.
What that means: “I can turn a backend API into a full-stack product: OAuth auth, file uploads, connected frontend and backend, tested and deployed with a clean Git workflow.”
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.
