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
0% commitment to quality
0 bugs left in production (this sprint)
0 + test cases written this week

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.
