AN INTERACTIVE QUALITY ENGINEERING PORTFOLIO

Explore quality.
/hands-on

Don’t just read about testing.
See what it catches.

Explore working demonstrations, investigate the evidence, and discover the engineering decisions behind reliable software.

TOOLS IN MY PRACTICEPlaywrightTypeScriptCypressPythonCI/CDAI quality

01 / FIND YOUR STARTING POINT

A lab for the curious.

Choose a topic. Understand the problem.
Explore the evidence.

01 INTERACTIVE DEMO AVAILABLE
»

Visual regression: a working example

Compare an approved UI with an intentional styling change. Explore what failed, why, and how the evidence helps.

→

Focus areas describe my practice. Only projects marked “Interactive demo” are available to explore today.

02 / STEP INSIDE THE DEMO

One change.
A clear signal.

A real recorded result.
A small interaction to help explain it.

001INTERACTIVE DEMO

Visual Guard

Catch what functional tests can miss.

A shopping flow still works—but its product titles have changed. Compare the approved UI with an intentional regression and inspect the result.

03 / THE THINKING BEHIND THE TESTS

A green check is useful.
Know what it proves.

My work spans test automation, web and API quality, and AI-assisted engineering. This lab makes those ideas tangible through small, focused demonstrations.

Each case study connects a testing decision to its outcome. The goal is to make quality easier to inspect, discuss, and improve.
