Backend & AI Automation Engineer at Rikkeisoft who automated test-document generation from large Excel specifications using LLMs.

What I'm looking for

I'm seeking a Java (flexible) Backend Engineer, Solution Architect, or Business Analyst role where I can apply my traditional architecture expertise alongside modern AI-automated development.

At Rikkeisoft, I architected an AI-driven testing automation system that uses GitHub Copilot and LLMs to generate test documents from large Excel software design specifications for Japanese enterprise clients.

I also wrote Python parsing scripts and custom Excel add-ons to prepare specification data for LLMs, using dynamic chunking and size calculations to work around context-window limits.

Earlier, at Rnd4u, I developed automated pricing logic and forecasting tools for a PriceFX / SAP E-Commerce project. I’m also developing a personal indie game and have created web comics and illustrations.
