Built as an employee of a company. The code and screenshots belong to the client, so I can't show them for confidentiality reasons.
The challenge
A management system for the wastewater treatment plants of an entire region. It collects and displays water quality parameters in real time: chemical levels, sensor readings and so on. It also came with years of legacy code.
What I did
Part of the job was maintenance and new features. The other part was cleaning up: I refactored critical modules without stopping operations, which matters when the system runs real water infrastructure.
