I’m thrilled to officially announce that Nathan McCauley and I are joining Docker to lead the Security Team. Back in 2011, Nathan and I were fortunate enough to join Square just as it was picking up steam. Square disrupted traditional point-of-sale systems by allowing anyone to take credit-card payments on their phone. And with great, disruptive ideas came new and interesting security engineering challenges. During our time at Square we built a wide range of different systems, from an general purpose cryptography infrastructure, a fully-fledged mutual-TLS micro-service architecture and a small end-to-end encrypted credit-card reader. All of these systems allow Square to move hundreds of millions of dollars per day. We are incredibly proud of what we have achieved at Square but a new opportunity presented itself.
