I taught myself to build. Then I taught myself quantum.

01 · The market

What mattered most wasn't written down.

I grew up on a market floor. The knowledge that mattered there wasn't anywhere online. You learned it by standing next to someone who had done it for thirty years. That stayed with me. I build for the people technology usually skips, because I was one of them.

02 · Teaching myself

I didn't find a shortcut.

In 2019 I joined an iOS bootcamp as a student, and six months later I was teaching it. I never found a shortcut. What I found was a way to learn, and I kept rewriting it until it held.

03 · The method

The four steps I use to understand something new.

1. 01Map the whole before any detail.
2. 02Explain it so a child's “why?” still has an answer.
3. 03Where your explanation stalls is what to study next.
4. 04Say out loud where you're only guessing.

The last step matters most. Being honest about where your knowledge ends is what lets anyone start.

04 · The grind

I learned it from the primary sources.

I worked through Nielsen & Chuang, Preskill's lectures and Mermin on my own, with no one to ask. Later I went to IEEE Quantum Week and sat with the people who write about this for a living. QuantumNative is the tutor I wish I'd had.

05 · What I've shipped

Things I've built for real people.

Woorinara is a civil-service app for foreign residents. It won the Excellence Award at Korea's 2024 Open Data Forum. Market-Mate turns a merchant's photo into a sellable story; its patent has been filed (not granted). SwiftQuantum is eight apps that put quantum tools on the iPhone.

06 · The rule

How I handle claims and mistakes.

Every claim is tagged. When I get something wrong, the correction goes in the same document, and I've done exactly that with my own security work. I have no credential to hide behind, so being truthful has to serve as one.
