Shingon Buddhist priest who codes. 25 years on the factory floor.

I sit with factory managers, figure out what breaks, and build systems that fix it. Over the past two and a half years, I independently delivered 30+ enterprise systems for a semiconductor materials manufacturer — MES, AI visual inspection (YOLO11), IoT automation, enterprise AI chatbot — all following ISO 27001:2022 principles.

Before that, I ran a software company for 19 years, delivering factory systems across 4 TSMC fabs and managing teams of up to 30 engineers.

25 years of factory knowledge, in one interactive system.

DashAI — the panel on the bottom right of every page. It reads live factory data, flags non-conformance reports with three ranked options, and schedules orders to the right production line. It does not summarize. It operates.

BCM Simulation — pick a disaster scenario and watch cascading impacts spread across departments in real-time. Full RTO/RPO matrix.

Agentic AI — 5 factory agents in a collaboration network. Scenario theater replays multi-agent decision-making.

A Shingon priest who codes, turning a 1200-year-old sutra into software.

shukuyo.dashai.dev

Kukai brought the Shukuyodo sutra from the Tang Dynasty to Japan in 806 AD. It maps how two people relate using 27 lunar mansions — where friction shows up, how to work around it.

I translated the original scripture into a working system. Every result links back to the source text in the Taisho canon.

Open-source SECS/GEM equipment driver in Go.

Started from reading SEMI specs for fun. Ended up implementing 12 standards, 5 protocols, and IEC 62443 security controls in a single static binary.

Builds on the work of secs4net, secsgem, secs4java8, and secs4go. Simulator-verified.
