Renata Gajzlerowicz is a Junior Full Stack Engineer and former QA Automation specialist with nine years of cross-functional experience delivering reliable web and API systems from Poznan, Poland. She transitioned from deep QA expertise—building E2E suites in Cypress, Playwright, and Pytest and managing CI with GitHub Actions—into full-stack feature work using NestJS, GraphQL, React, Apollo and Tailwind. At Saleor she contributed end-to-end tests to a high-performance open-source headless commerce core and dashboard, improving checkout and dashboard reliability for real-world commerce scenarios. Her background spans both manual and automated testing across startups and product companies, bringing a pragmatic focus on testability and maintainability to feature development. Renata’s blend of hands-on backend API design and front-end delivery, plus experience with Dockerized test environments, helps her ship resilient features that are validated by automation. She pairs a methodical QA mindset with curiosity for product-facing code, often spotting edge cases before they reach users.
