I build working platforms from zero.
Concept, design, code, and operations — solo.
Products I started myself — from architecture and implementation through to automated operations.
Nail salon discovery platform for visitors to Japan
Built from concept to production. English-first content, structured so that AI assistants can cite it accurately (AEO).
Name withheld
A matching platform connecting practitioners with venues. Registration, screening, visit, contract and go-live are handled as a single flow, with the operator in the loop. Includes an admin dashboard and automated emails triggered by confirmed dates (idempotent, dispatched every morning).
LINE × AI booking SaaS for beauty salons
AI built into the LINE Official Account, automating everything from the first inquiry to a confirmed booking. Flat monthly pricing with zero per-booking commission.
Operations system for hotels and ryokan
One system for reservations, rooms, guests and customer records. Designed around the screens staff actually touch every day — drawn from 13 years running hotel operations. Multilingual, with an AI concierge and document export built in.
* Some project names are withheld for contractual reasons.
Responsive landing page built with Elementor. Mobile-first design optimized for booking conversions.
Full redesign of an existing WordPress site with modern UI and internal SEO improvements.
Theme customization and UI adjustments to match brand identity. Added custom functionality.
AI chatbot trained on internal company documents. Automates employee inquiries.
Fast, accurate, and professional. Shingo understood exactly what we needed and delivered beyond expectations.
Clear communication throughout the project. The technical explanations were easy to understand, and the post-delivery support was excellent.
Unlike other developers, Shingo brings a business perspective to the work. Not just a builder — a real partner.
