About me
Japan-based web engineer with 20+ years of experience. I rescue AI-generated and existing web apps that are stuck, insecure, or not ready to launch.
I fix Next.js and React apps, secure Supabase authentication and RLS, integrate Stripe payments and subscriptions, and add OpenAI or Claude features.
I run a web business with $1M+ lifetime revenue and 1M+ monthly pageviews at its peak. My workflow is AI-assisted, then personally reviewed and tested.
You get a clear fixed scope, async communication through Fiverr messages, and a practical plan within 24 hours. No meetings are required.
