I was Yasuko's manager for 3.5 years. Yasuko was a core member of our teams/squads following an Agile highly collaborative and available work process from requirements definition through QA and launch. Our teams could not have delivered as quickly and to same level of quality with Yasuko. She was a key accelerant for us. Yasuko is very detail oriented and organized. Her knowledge of all OpenTable's systems was expert level. Yasuko often worked on multiple projects and teams at the same time and has the planning skills to balance competing priorities and deliver on time. Yasuko has good communication skills and she and I developed a good working relationship to understand priorities and how to tradeoff availability. Before COVID Yasuko grew her skills to become an automation engineer. Yasuko learned Cypress.io, javascript, GitHub and a number of other technologies. Yasuko built out the test suites, fixture data and credentials to run e2e tests for customer facing applications. She not only worked close with the engineers but became an engineer. This was not an easy set of skills to acquire but Yasuko stuck to it and became a pretty solid automation engineer. This is a testament to her dedication and work ethic. Finally Yasuko is a fun and caring person who cares about the customer and her teammates.
