Rockstar🎓
Top SchoolSenja Jarva is a senior software developer based in Helsinki with 11 years of experience specializing in front-end engineering and test automation. Currently at Finnair, she brings practical expertise in improving developer tooling and code quality, particularly through rigorous ESLint rule fixes and test-suite refinements. Her open-source contributions to well-known linting projects—testing-library/eslint-plugin-testing-library and eslint-plugin-react—demonstrate a knack for diagnosing false positives, preventing leaked renders, and expanding DOM attribute coverage. Senja pairs a strong academic foundation from Aalto University with hands-on QA engineering instincts, making her equally comfortable writing tests as she is improving developer ergonomics. Colleagues rely on her to spot subtle testing pitfalls and hard-to-reproduce lint issues before they reach production.
