Biography
I'm a developer, technical team leader, and architect. I started a career before StackOverflow existed. For over 17 years, I've been creating systems close to the business process. I believe that Event-Driven Architecture and Event Sourcing are great ways to achieve that.
I'm an active open-source developer active especially in the Event Driven space (I was working on tools like Marten, EventStoreDB, and now Emmett). I'm sharing my journey and findings on my blog https://event-driven.io and practical samples at https://github.com/oskardudycz.

Pragmatic Event Sourcing
Talk
Event Sourcing is complex and brings additional overhead! Have you heard that? Oskar did, and is fed up with it.
Oskar will show you Event Sourcing in the raw form, without Clean Architecture fluff, focusing on what it brings: synergy between modelling, coding and adding your business observability.
We'll do a full transition from modelling to expressing it in the code, testing, and wrapping it in a simple but real-world application.
You'll learn how repeatable patterns for handling business logic can actually speed up your development, reducing the cognitive load and bringing domain expressiveness to code.
