Build, evidence & learning

Developed with AI assistance. The recorded checks were run by the assistant against local test services. Independent hands-on practice is the next step.

The code includes repeatable tests, bounded checks and saved JSON/HTML reports. No employer systems or customer data are used.

Earlier work: device-monitoring prototype

I defined the requirements and reviewed how device inventory, status checks and reports are presented.

Implementation was AI-assisted. I reviewed device readings, flagged missing or stale information and guided refinements. The prototype has not established production reliability or measured time savings.

BEYOND WORK

A creative side.
