What I'm looking for

I'm looking to own quality end to end: designing release-blocking automation, test strategy, and CI/CD quality gates across API, UI, database, and E2E systems. I value teams that involve QA early in architecture and design decisions.

At Fortress Information Security, I build release-blocking quality gates across GitLab CI and Jenkins so bad code does not ship. My work shortened deployment cycles by 31% and reduced API defect escape rates by 73%.

I architected API, UI, and end-to-end automation frameworks using Robot Framework, PyTest, Selenium, Playwright, Python, and TypeScript. My API suite grew to 4,000+ tests and 70%+ REST endpoint coverage, while the UI framework raised coverage from 38% to 62% and cut manual QA effort by 79%.

I bring QA into architecture and code reviews early, combining exploratory testing with automation, contract testing, database validation, and performance testing. I also use OpenAI and Anthropic APIs for test-data generation, anomaly detection, and automated file comparison, reducing manual analysis time by about 40%.

Previously at Intetics, I built scalable Python, Selenium, and PyTest frameworks for concurrent client projects, delivering 500+ automated tests and reducing manual effort by 53%. I also built ProseHire end to end in Django and write Break It on Purpose, a weekly newsletter about bugs, CVEs, and QA.

Pipeline & CI/CD Engineering:

- Designed release-blocking quality gates in GitLab CI and Jenkins across three frameworks. Bad code didn't ship. Deployment cycles shortened by 31%.
- Built parallel execution pipelines with worker pools for Playwright (TypeScript) and PyTest (Python) suites, cutting regression runtime without touching coverage.
- White-box testing, unittest.mock, and contract testi
