As a Director of Engineering and Staff Engineer at Reddit, I have solved diverse problems at scale. I have experience managing large-scale engineering projects and overseeing the development of new features and technologies for one of the world's most popular social media websites. Prior to my work at Reddit, I spent years working on mission-critical backend infrastructure systems at Groupon, Bank of America and Motorola. I also have a decade of experience researching technology in biology curricula at research universities.
