Product Analytics for Meta's Messenger texting quality.Lead Data Scientist of Meta's Messenger App in charge of texting quality. Focus on messaging reliability and latency across the family of apps (Messenger, Facebook, Instagram, and Facebook Lite) and across all surfaces (iOS, Android, Web).Responsible for maintaining high quality user experience as users are transitioned from open to encrypted texting. DS Technical Lead of a major experiment with ten core members consisting of software engineers, technical project manager, data engineers, and data scientists. As the lead, I managed all DS facing functions, including prioritization of DS tasks, constructing the measurement plan, resolving DS execution questions, reporting of metrics to Engineering leadership, and socializing the findings to the larger Messenger organization. As a result of my leadership, the project was able to stay on path despite facing multiple implementation and experimental rollout headwinds.One of the analytical challenges was that the experiment was not able to randomly sample the user base due to privacy constraints. As a result, the findings from the experiment did not easily translate to the broader organic user base. I identified and articulated this difference and proposed a stratified sampling approach to put the data from the experiment on similar footing as the organic users of the service.
