The development approach
Find the cause.
Verify the change.
Tools help move the work forward. A repeatable process makes the result understandable.
From problem to verified behavior
- 01
Reproduce the problem
Describe the expected behavior and the actual result. Find an input or sequence that makes the failure repeatable.
A concrete failing example. - 02
Isolate the cause
Trace the relevant interface, request, response, and data. Narrow down where the behavior diverges from the expectation.
An explanation of the failing boundary. - 03
Make a focused change
Change the smallest useful part. Keep assumptions visible and use AI-assisted tools to explore and implement the solution.
A change that can be reviewed. - 04
Verify the behavior
Add a meaningful regression test. Check the working path, failure states, accessibility, and layout where the change affects them.
A result with evidence behind it.
An example from this portfolio
Two strings.
One overlooked duplicate.
The import inspector accepts contact records. Different capitalization and extra whitespace can hide a repeated email address.

AI-assisted development
Keep the reasoning
close to the result.
AI can help investigate, implement, and write tests. I aim to keep changes small enough to inspect and explain, then verify the behavior.
