About Yusaku Kasahara

I am a QA Engineer who has built QA departments from scratch with effective manual and automation test strategies. I handle testing duties for multiple teams at once with automated (Cypress, Selenium Webdriver) and manual testing (Exploratory,design, API) contributions. I thrive when given direct communication channels with product, developers, and designers, ensuring testing is performed early in the product development cycle in order to maximize delivery speed and minimize costly bug fixes late in the feature release process.
