What I built

• Independently built the core Java data-validation framework using Selenium and Appium, now used by 1,700+ automated validation tests. The framework supports Roku, Android and web.
• Personally authored 400+ web data tests included in that total.

How teams use it

Multiple teams run the required Jenkins gate several times daily. The centralized test repository supports collaboration across time zones.

How I investigate missed issues

When an issue escapes, I review results across environments to find the earliest detection and understand why it was not escalated. Human review confirms whether a signal is a real issue.

Starting point

The work spans both creating automated tests and investigating existing failures. I started with Markdown skill files containing reusable instructions, then expanded them into agent instruction files for a dedicated data-automation subagent.

How the workflows work

• For a new test, the subagent receives the context for a QA test-library case, creates an automated test, executes it, applies fixes and reports the results.
• For a failing test, a repair-and-retest workflow supports diagnosis, applies a fix and runs the test again.
• A customizable workflow template connects ticketing, test-case management and chat.

Making it useful to the team

I maintain the agent and support adoption through workshops, guides and templates, with reusable skills for Cursor, Claude and GitHub Copilot. Every engineer on the automation team uses the agent daily.

Human review

Engineers review the results and verify real issues before escalation. The workflows support test creation, diagnosis and repair while keeping engineering judgment in the process.

The starting point

The developer-built framework covered basic sign-up checks and needed renewed maintenance and broader coverage. As the team’s sole QA engineer, I took on its expansion and ongoing operation.

What I changed

I used my automation experience to expand and optimize the existing framework. I added test cases and scenarios, enabled parallel execution, and brought the framework under QA ownership and operation.

The result

Test-case and scenario coverage tripled, and overall automation runtime fell by 75% with parallel execution.

Wider responsibility

As Senior Test Analyst, February 2020–June 2021, I handled QA for Battle.net Identity across account creation, login, settings, recovery, OAuth and authentication APIs. I coordinated testing across identity products and created email notifications driven by telemetry from the system.
