Presentation: "Engineering Elegance: The Secrets of Square's Stack"

Track: Tales from Silicon Valley

Time: Thursday 17:20 - 18:10

Location: Seacliff AB

Abstract:

In 2010, NY Times columnist David Pogue described Square as ""beautiful, simple and a joy to use."" Square's dedication to user experience continues to strike a chord. Today, more than 2M merchants and individuals use Square to process $6B annually.

How does Square deliver its trademark seamlessness? Simple. By routinely tackling daunting engineering challenges, shielding merchants and payers alike from the inherent complexities of payment processing.

Bob takes the audience on a tour of Square's stack, tracing the payment lifecycle from end to end. From magnetic stripe decoding to multi-homed data centers, Bob talks about lessons learned–what worked and what didn't–and the variety of technologies and open source frameworks concealed behind Square's simple façade.
