    Indie developer in Japan. I run ja-normalize, a live x402 pay-per-call API + MCP server for Japanese business data (addresses, names, bank codes, holidays), and package what I learn shipping it as skills: x402 monetization, Japanese data handling, and Japanese back-office work (keigo, invoices, 稟議).
