Jun 2020Engineering Dropbox Transfer: Making simple even simplerThis post details the engineering journey of building Dropbox Transfer, a new product for sending large files. It covers the ideation phase, driven by customer feedback and the realization that file sending has different use cases than file sharing. The engineering approach involved a two-stage process: first, a throwaway prototype optimized for learning and flexibility, built by forking existing frontend code and making minimal backend changes. This prototype was validated using the Sean Ellis score. Second, the development of the enduring product, which leverages existing Dropbox storage and abuse prevention systems but required building new product behaviors for sending, including download notifications, sender statistics, ephemeral links, and password protection. The post emphasizes the importance of customer understanding in engineering decisions and the concept of code quality as a spectrum, advocating for pragmatic solutions that align with customer needs.
