Background

About Daniel MacIejewski

With 13 years of dedicated experience in software quality assurance, including over 5 years specializing in building automated testing solutions, I am a Senior QA Automation Engineer interested in delivering high-quality, efficient, and reliable software. My journey has equipped me with a deep understanding of the entire SDLC and the critical role automation plays in accelerating release cycles and elevating product quality. My core expertise lies in designing, developing, and maintaining sophisticated tests using JavaScript and Node.js-based technologies such as Puppeteer (Mocha, Chai, Jest), Playwright, and Cypress, alongside experience in Selenium. I thrive on solving complex testing challenges, consistently increasing test coverage, and optimizing CI/CD pipelines to ensure faster, more stable deployments. Beyond the code, I believe collaboration is key to success. I have years of experience working within Agile environments, leading UAT processes, and mentoring teammates to create quality products. My background in Management Information Systems provides a strong analytical foundation, enabling me to bridge technical solutions with business needs.
