Architecture, journeys and technical decisions focused on operational results.
SCADA, PLC, IoT, automation and signal reading for real processes.
I connect engineering thinking, digital product and operational context to turn messy requirements into usable systems.
This is not a portfolio. It is not a services page. It is a working laboratory.

Verified run · Execution report
Run python .proof/record.py after installing the prerequisites above. The scenarios execute repository code and verify exit codes and expected output. CI publishes execution-proof with the transcript, input fingerprints and source commit. The downloadable report identifies the exact tested version; the workflow badge tracks the latest run.
