Electrical engineer & software developer
From Physical Systems
To Practical Software.
I’m Harry. I work across industrial machinery, software and data — understanding how systems behave, then building ways to make them work better.
Real equipment. Working software.

An Engineer Who
Builds Software.
Some problems start inside an electrical cabinet. Others start with a dataset, an interface or a workflow. My background in electrical engineering and computer science lets me work across those boundaries.
This portfolio follows the decisions behind each experience — from initial investigation to implementation and testing.
