Always a Student is one of Clever's culture tenets: we love to learn, and this blog is where we share what we learn on topics that matter to engineering, from small but critical technical details to how we organize our engineering teams. This blog is cross-published on Medium.

However, as with many facets of JS, modules grew organically from the developer ecosystem (as opposed to being designed as part of the language from the beginning), so they have their flaws – one being that you can […]
At Clever we help 1 in 6 schools in the country sync data on an hourly basis from their student information systems (SISes) to the ed tech apps that their teachers and students use. These 20,000 schools sync about 50 GB of data in aggregate – that’s over a terabyte of data per day. While […]
