About
Who I am
Hi, I’m Inkyu Oh. 👋
I studied musicology, computer science, and design at Seoul National University. An internship at the Music and Audio Research Group was where I found my way into computing. I then spent 3.5 years as a backend and AI engineer at a fintech company serving 120M+ users.
I’ve been an inventor since I was a kid: when something is inconvenient, I build my way out of it. For years that meant productivity tools that remember for me, type for me, and keep distractions away. But the goal was never to produce more. It was to clear the way for the real work: thinking. Now that AI can produce for us, that goal is clearer than ever. I build tools that make room for thinking.
I live in France now, and I love the water, especially . 🤿
