I build tools Monash students use, and write down how they run.
Backend and AI application developer. I run Monash Hub on my own VPS, with automated deploys that roll back when a release fails, and wrote 182 of the 203 merged pull requests in SecureView, our final year project.
Writing
How my projects are built and run, with the code linked. Every post has an English and a Chinese version.
SecureView
Sharing files the server cannot read
In SecureView the browser encrypts every file and the server never holds a key that opens one. How sharing works under that rule, and what happens when someone forgets their passphrase.
Monash Hub
Unit ratings without sign-in, and keeping them honest
Students can rate a unit without an account. How one browser keeps one rating per unit, why the limit is on the network and not the key, and what this still does not stop.
Monash Hub
Translating the Monash Handbook without paying for it
Five thousand units and hundreds of official pages, translated into Chinese for free. Why a glossary sits in front of the model, and how a bad translation falls back to English.
Monash Hub
How Monash Hub deploys itself and rolls back
One VPS, no one watching the deploys. How the deploy script checks the right commit is live and puts the previous images back when it is not.
