AI-assisted QA
From individual test cases to confidence across the whole product.
My work spans desktop dispatch software, real-time passenger information, and enterprise web and mobile applications. I combine hands-on functional testing with integration checks, backend data validation, AI-assisted code review, and collaboration with developers and product teams.
I care about finding the failures that happen between components: the data that doesn't sync, the edge case a happy path misses, and the release risk hidden in a code change. My approach connects testing discipline with a practical product mindset.
Test for risk
Use impact analysis and edge-case thinking before execution begins.

Key project · CleverCAD & BusTime multi-system integration
-
Conducted end-to-end manual, functional, and interoperability testing
between CleverCAD (Windows
.exeComputer-Aided Dispatch application), BusTime (real-time passenger information web app), and connected transit modules, achieving a 98% defect-free release rate. - Conducted deep Pull Request (PR) code reviews and leveraged AI assistants (Cursor, Claude, ChatGPT, Copilot) to cross-examine code changes, map impact zones, and predict edge-case failure risks before test execution.
-
Managed complex test setups across multiple remote Virtual Machines (VMs)
simultaneously using mRemoteNG—deploying and configuring
different versions of desktop
.execlients alongside web environments to verify multi-project deployments and live application interactions, improving test execution efficiency by 35%. -
Simulated real-world dispatch and fleet operations (route detours, schedule
adherence, emergency alerts, and operator messaging) in the desktop
.execlient and validated live data synchronization with web modules and passenger displays with 99.9% accuracy. - Executed backend database validation using SSMS and SQLCMD, querying SQL databases to confirm UI actions accurately updated route schedules, vehicle states, and event logs, identifying 40+ critical data-sync defects pre-release.
- Created and executed detailed test cases, logged defects in JIRA, and collaborated with developers, Product Owners, and product teams for efficient issue resolution, reducing defect turnaround time by 30%.
