Ever wondered how your scribbles on Snapchat turns into a smooth line, or how the pen tool works in Figma or Procreate? In this talk we'll dive into the invisible art of line-drawing algorithms.

We'll start from the historical pixel-based methods to the tools that we use today, wrapping up with real-world examples.

The techniques described are evergreen, timeless and cross-platform.

It's pretty common to evaluate new changes with a vibe check but that makes it difficult to really know what's up with your system. We'll talk a bit about how to build more complex apps.

If you've worked in technology for longer than a couple of years, you'll have taken a ride on the architectural see-saw. After throwing out your monoliths with the proverbial bathwater and going all in on microservices, you decide that actually the microservices suck too and you're going back to the monolith.

In this talk, I'll provide insight into backends for databases, and why many organizations are starting to create their own graphql-based data supergraph.

How are you doing your tests? Are you effectively covering all use cases and their unique nuances? How many times have you broken everything? 

Let's delve into the complexities of testing a federated supergraph at scale, discuss on what are the issues and limits of testing GraphQL today and options for improving testing and increase confidence.
