CipherRank

A study app that turns CompTIA exam prep - Security+, Network+, and the newer SecAI+ - into something you actually come back to. It shipped to the App Store with a hand-built question library.

There’s an AI generation pipeline behind it too, with two-stage validation so a bad generation never reaches a user, but I’m still tuning its pass rate before it goes live in a release. The shipped version runs on curated content.
