Hot Work Permit System

A web permit system for hot work in a smelting plant. It replaces the paper permit for a high-risk task.

Client: PT Smelting Gresik
Year: 2024
Role: Developer (internship)
Field: Industrial Safety / Laravel

The internet reaches this system. The console measures it below. I run a public instance of this system. The figures below come from it, not from the plant.
