Turn Fintech APIs into Real-time Experiences - Findevr 2016

Jax Finance 2016
Our brain craves for information that changes at least twice a second. This should be enough to explain why most recent successes (Waze, Uber) present a real-time UI. In Finance, time is money, and real-time is real money: offering real-time UX also changes market dynamics, by short-cutting insiders that can no longer benefit from information assymmetry. All this is made possible by a conjunction of technologies that have now reached maturity: reactive frameworks, streaming, standard data format -even for differentials, and HTTP/2 will only accelerate this trend. As an illustration, I will review an example of an end-to-end event-driven application, then review Devops recipes for trunking APIs.
