Kazuna B

Japan-based developer (native Japanese). Websites, iOS apps, AI chat tools and short videos.

I’m Kazuna Baba, based in Niigata, Japan. Japanese is my first language. My English is conversational, and I’m most accurate in writing.

What I make:

• Websites and landing pages with Next.js/React on Vercel, including structured data (JSON-LD) for search and AI search
• AI reception/chat tools for websites: AI sorts the question, and replies come only from pre-approved text, so it doesn’t make up prices or promises
• iOS apps with SwiftUI. Two of my own apps are live on the App Store
• Short vertical videos for TikTok and Reels
• Japanese pages for brands coming to Japan: Japanese landing pages and natural Japanese copy

Everything in my portfolio is my own project, not client work.

How I work:

• Scope and price are fixed before I start.
• Revisions are unlimited until launch (delivery), within the scope we agree at the start. Additions or a full redo are quoted separately.
• For websites: first version in as little as 2 days after the materials and payment are ready.
• About 30 hours a week, remote. I check messages every day (JST).

Not a good fit: Shopify builds, large e-commerce, heavy systems such as membership or booking platforms, on-site photo shoots, and same-day delivery.
