Sound familiar?
- A core system is old and hard to change, but it cannot stop, so you need a migration plan in clear phases rather than a risky rewrite.
- You want AI features, documented: how they are evaluated, what they cost to run, and what happens when they are wrong.
- You need a detailed quotation and specification before any work starts.

Questions
Can you provide a detailed estimate before we start?
Yes. Every engagement starts with a fixed-price scoping step that ends in a written plan: phases, deliverables, risks and costs.
Do you work in Japanese?
I work in English. Specifications and reports can be prepared for translation, and I work well with a bilingual project lead on your side.
How do you report progress?
In writing, on a fixed rhythm: what was done, what comes next, and any risk that needs your decision.
