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 no layers between you and the person writing the code.
BUILD
Weeks, not months
Pair-programming, automated review, and generated tests compress build time without cutting corners. Work an agency staffs three people on, I ship alone. The savings land in your quote, not my overhead.
RANK
Google indexes you. ChatGPT recommends you.
Shoppers now ask ChatGPT, Claude, and Gemini what to buy. I structure your storefront — schema.org data, clean semantics, llms.txt, answer-ready content — so AI assistants can find, quote, and recommend your products.
SHIP
A person ships it
Every line is reviewed, tested, and deployed by the same senior developer you email. No juniors, no handoffs, no black box.
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.
Structured so AI assistants can quote them, too — the same treatment your store gets.
No. Shopify storefronts are the deepest specialty here, but the same stack ships custom websites, web apps, and API integrations — Next.js on Vercel, GA4 analytics, and SEO built in. If it lives in a browser, it can be built here.
Typical storefront builds land between $2,500 and $18,000 depending on scope — essentials builds from $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: a flat, fixed price before work begins, usually well under agency rates for the same scope. Monthly care plans for ongoing management start at $490 — the Base plan protects your site and keeps its launch SEO intact, while Summit and above add active SEO and AI-search growth work.
Most sites and storefronts launch in 2–8 weeks depending on scope. AI-assisted development compresses build time without cutting corners — every release is human-reviewed and tested.
AI assistants like ChatGPT, Claude, and Gemini increasingly answer shopping and buying questions directly. I structure your site’s data and content — schema.org markup, clean semantic HTML, llms.txt, answer-ready copy — so both Google and AI assistants can find, quote, and recommend what you sell.
Yes. Migrations, rebuilds, performance rescues, and care plans for sites and stores I didn’t originally build are all common projects.
