REMOTE COLLABORATION

Serving Businesses in Tokyo & Japan

I work remotely with companies in Tokyo and across Japan, supporting new software projects, existing PHP applications, API integrations, and e-commerce setups. For Japanese-language projects, business logic and localized terminology can be provided or reviewed by your internal team or native specialists to ensure absolute correctness.

If your company already has a PHP application but needs new integrations, better performance, or a more maintainable architecture, I can work with the existing codebase and improve it without necessarily replacing the entire system.
