Available to hire
I’m Nigel Bautista, a Senior SDET/Software Engineer in Test with 12+ years of experience transforming software delivery by shifting quality left. I specialize in embedding quality gates early into CI/CD pipelines and building robust test automation frameworks with Playwright/TypeScript and GitHub Actions. I’ve led teams, migrated hundreds of legacy Java/Cucumber tests to modern Playwright TS, and helped organizations achieve near-zero production defects while accelerating release velocity.
My approach centers on pre-merge quality enforcement, ensuring every pull request is green before merging. I design scalable test architectures, automate end-to-end and API tests, and champion a culture where quality is everyone’s responsibility.
