Mior's Mission 9: Build a Social Media API certificate
This certificate was awarded to Mior on 9 October 2026 for completing Mission 9, Build a Social Media API, at Sigmaschool.
What that means: “I can build an authenticated social media API with SQL relationships, issue and verify auth tokens, and enforce authorization rules on protected routes.”
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.
