The domain of Payments, Finance, and more generally FinTech, is a fast-growing industry that reached record global investment of $111.8B in 2018. The underlying technology that powers this incredible growth is also evolving rapidly. Hosted by Uber, MoneyCon 2019 brought together engineers from leading tech companies to present on the latest topics in payments engineering.
In this talk during MoneyCon 2019, Dropboxs Kirill Sapchuk and Evgeny Skarbovsky discuss how revenue optimization (fighting involuntary churn) has evolved at Dropbox over the last few years from some simpler ideas and experiments around retries up to an ML-based approach that they are working on today.")

To facilitate the growth of Uber’s global operations, we need to be able to quickly store and access billions of metrics on our back-end systems. As part of our robust and scalable metrics infrastructure, we built M3, an open source metrics platform that has been in use at Uber for several years now. During this talk, engineer Nikunj Aggarwal walks through what a general metrics pipeline looks like and how M3 components can be used for the various stages of the pipeline without locking you in to a particular vendor. He also covers some of the unique challenges we face at Uber’s scale and how the learnings from those can be used by other companies.
