A GUI for configuration data that should be easy to change.
Deltaskin Editor turns simple JSON configurations into a focused visual interface. It exists because the underlying data was approachable, but there was no good GUI for the work of seeing, editing, and testing it.
My contribution
SCOPE OF WORKEditor design
Making configuration data legible and editable through a direct visual interface.
Workflow problem-solving
Building a specific tool where the available editors did not match the actual need.
AI development experiment
Using the project to explore an evolving development workflow from GPT-4 through early agentic work.
Simple data still needs the right interface
The configuration itself is simple JSON, but a raw file is not always the right place to make a decision. Deltaskin Editor gives the data a visual form so it can be understood, adjusted, and tested without treating every change as text manipulation.
A record of changing development tools
The first version began before coding agents were part of the workflow. Its later iterations became an experiment in AI development, beginning with GPT-4 assistance and continuing into the earliest agentic approaches. The goal stayed grounded: make a small application that solves a particular problem well.
