Breaking software so you don't have to. I design test strategies, automate the boring parts, and chase bugs until they confess.
About me
Hello! I'm Barbara, a Quality Assurance Software Engineer who genuinely enjoys finding the edge cases everyone else overlooked. I believe great quality isn't a phase at the end of a sprint — it's a mindset baked into every commit.
My day-to-day mixes manual exploratory testing, automated test design, and close collaboration with developers and product folks to ship software that just works. I care about clean test architecture, fast feedback loops, and writing the kind of bug reports that get fixed on the first try.
When I'm not testing, you'll find me:
- Tinkering with new automation frameworks
- Reading about reliability engineering
- Drinking a strong coffee while reviewing test reports

What I do
End-to-end test automation
Designing reliable, maintainable automated test suites that catch regressions early and run fast in CI.
Manual & exploratory testing
Going beyond the test plan to find the edge cases that only show up when a real human pokes around.
API & integration testing
Validating contracts, payloads, and error handling so the backend never lies to the frontend.
Quality advocacy
Embedding quality into every step of the SDLC — from grooming to retrospective.
