How Zencity grown from a single client in southern Israel to serving more than 130 million citizens On three continents - from the data perspective. We’ll talk about how we’ve started and the initial choices you need to make. And how we’re working on scaling a product from a single-digit number of clients to our current scale. About what happens when eventually the original setup doesn’t work anymore, new requirements appear, and the landscape changes. We’ll candidly discuss our stopgap measures and some of our missteps and wrong choices. We hope our experience will help others in their path.

• Ori Roza: A new way of testing web frameworks (20 min) slide as pdf - slides as pptx

In this talk we will see a new way of testing web frameworks which gives us the ability to treat endpoints as they where a simple functions, with this ability, we can catch simple exceptions and outputs without the web framework layer which gives us simplicity and observability. We will go over a case study of Django web framework. using this package
