# Lei Zhu > Staff Software Engineer at Reddit Location: San Francisco Bay Area, United States Profile: https://flows.cv/leizhu As a lead, I always value my team and customer. As a software engineer, solution first is always my philosophy. Being able to make sharp decision on what, when or how to do to solve a problem aren’t enough, as always, I tend to make it real by participating in every single step of implementation.
