I'm not a developer. I'm building software anyway.

I'm a solo builder in South Korea. I'm not a developer — I've never shipped production code on my own. And I can't hop on a sales call in English and pitch anything convincingly.

For most of the last decade, that list would have been a wall. You couldn't build software without engineers, and you couldn't sell it globally without being able to talk to customers. Both of those are quietly changing, and I want to find out how much.

Here's the bet. AI has gotten good enough that one non-technical person can actually build and ship a real tool. Platforms like Shopify handle the discovery and the payments, so I don't need a network or a sales team to reach people. And everything customer-facing — the writing, the support, the docs — can happen in text, on my own schedule, in whatever language it needs to be. If all of that holds, then the things that used to disqualify someone like me don't anymore. What's left is just doing the work.

I don't know if it holds. That's the honest part. Maybe the tools I build never find anyone. Maybe "solo founder plus AI" is more hype than substance and I hit a wall I can't code my way around. Maybe I ship something and no one wants to pay for it. I'd rather find that out in the open than quietly — so I'm writing it all down here. What I build, what breaks, what I get wrong, and whatever the numbers actually turn out to be.

The first thing I'm making is small on purpose. It's a Shopify app that checks a store's product catalog for the dull problems that quietly pile up: products with no image, descriptions that are basically empty, items missing a weight or an SKU, things filed under the wrong type. Nothing glamorous. But a messy catalog costs a merchant real money — in search, in trust, in orders that never happen — and fixing it by hand is tedious. It's also small enough that one person can actually finish it, which right now matters more than ambition. I'd rather ship one boring, real thing than plan a big one I never complete.

So that's the starting point. Not a grand vision — one small tool, built out loud, by someone who's supposed to be at a disadvantage and is betting he isn't anymore.

If any of this sounds familiar — you're building alone, you're not the obvious person to be doing it, you're working it out as you go — follow along. I'll be posting the real version: the parts that work, and the parts that don't.

More soon.
