# Jay Zhang > Software Engineer Location: San Francisco Bay Area, United States Profile: https://flows.cv/jayzhang1 I am an aspiring software engineer with a background in analytics and strategy. I enjoy solving complex problems and love the logic process of breaking down the problems into manageable pieces and planning steps to tackle them. I would like to make an impact by building great software products. I got into software engineering by my previous consulting work and my desire to make greater impact. During my previous consulting experience, I practiced my problem-solving skills by helping pharmaceutical clients to craft launch strategy, measure performance and build commercial operation infrastructure.
