«Open Bank Project: Open source, open data, global banks, Scala and transparency. How did that happen? (Lightning Talk)», Simon Redfern
When Open Bank Project was first pitched to a Berlin tech conference in Feb 2010, people liked the idea of easier programmatic access to bank accounts and greater financial transparency - but they questioned what regulators would think. Now, with PSD2 regulation coming into force, Open Banking is starting to become a reality in Europe and beyond. In this talk, I’ll describe how a bootstrapped Berlin based startup used Open Source, Scala, singing banks, synthesisers and hackathons to become a supplier to some of the largest banks around the world and influence government policy. I’ll demonstrate the Scala / Lift Web based Open Bank Project APIs, API Explorer and other components and touch on how we use Kafka and Akka to connect to core banking systems. (30 - 45 mins)

«Integration testing of REST services using Akka Http», Noam Almog
Testing REST services is hard, setting up environment, executing multiple remote calls, matching results on various encodings and formats and handling tests flakiness while trying to retain an easy to maintain and understandable code base. In this talk I will present how we designed our framework using akka http to handle many of those aspects. Through the design you will gain a glimpse of how we test and maintain over 200 microservices in production.
