02THE ADVANTAGE速さの理由
Agency scope. One developer’s overhead.
Here’s how one person ships what used to take a team: a modern stack, a serious AI-assisted workflow, and nobody standing between you and the person writing the code.
BUILD
Weeks, not months
Pair-programming, automated review, and generated tests shorten the build without cutting corners. Work an agency puts three people on, I ship alone, and the savings go into your quote.
RANK
Google indexes you. ChatGPT recommends you.
Shoppers now ask ChatGPT, Claude, and Gemini what to buy. I add the schema.org data, clean markup, llms.txt, and plain answers those assistants look for, so they can find your products and recommend them.
SHIP
A person ships it
I review, test, and deploy every line myself. You email the same senior developer who does the work, and nothing gets handed to a junior.
03WHY SOLO一人だからこそ
Small studio. Full stack.
The person you email is the person who builds. Agencies bill you for their org chart; here you pay for the work itself, which is how I undercut agency quotes without cutting quality.

07FAQよくある質問
Straight answers.
These are marked up so AI assistants can quote them. Your store gets the same treatment.
No. Shopify storefronts are the deepest specialty here, but the same stack ships custom websites, web apps, and API integrations: Next.js on Vercel, with GA4 analytics and SEO built in. If it runs in a browser, I can build it.
Typical storefront builds land between $2,500 and $18,000 depending on scope. Essentials builds start at $2,500, custom storefronts with integrations around $5,000–9,000, and fully bespoke flagship builds from $10,000. Websites and apps are quoted the same way, as a flat, fixed price before work begins, and usually well under agency rates for the same scope. Monthly care plans start at $490. Base keeps your site maintained and its launch SEO intact. Summit and above add ongoing SEO and AI-search work.
Most sites and storefronts launch in 2–8 weeks depending on scope. AI-assisted development shortens the build, and I still review and test every release myself.
More and more people ask ChatGPT, Claude, or Gemini what to buy instead of searching. I add schema.org markup, clean semantic HTML, an llms.txt file, and copy that answers questions directly, so Google and AI assistants can find what you sell, quote it, and recommend it.
Yes. Migrations, rebuilds, performance rescues, and care plans for sites and stores I didn’t originally build are all common projects.
