Deric Yee's Mission 1: Build Your Developer Portfolio Page certificate

This certificate was awarded to Deric Yee on 9 July 2026 for completing Mission 1, Build Your Developer Portfolio Page, at Sigmaschool.

What that means: “I can build a personal portfolio page with HTML and CSS, add a JavaScript greeting, and explain every line of it.”

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.
