Joe Onn Lim's Mission 7: Build a Movie Search Application with Live Data certificate
This certificate was awarded to Joe Onn Lim on 21 September 2026 for completing Mission 7, Build a Movie Search Application with Live Data, at Sigmaschool.
What that means: “I can fetch live data in React, manage loading and error states, and build a responsive search experience from derived results.”
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.
