We provide course about Boost your Architecture by Test-Driven Development. This is a hands-on training on how to use Test-Driven Development (TDD) to boost the architecture of your projects.
Content:
The course covers writing unit, integration, and end-to-end tests, showing how you can guard and enforce the rules of your architecture. We show the ways TDD helps with building and improving sustainable architecture. JUnit, Kotest, and Spock frameworks are used in the examples, however, the knowledge gained during the course is easily applicable to other testing libraries. During the course, attendees will learn about the challenges of maintaining a huge number of tests in a project, and how to avoid the usual pitfalls.

Instructors: Vadzim Prudnikau and Marek Dominiak
Vadzim Prudnikau is a Hands-on Architect, IT Trainer, and Conference Speaker with 20+ years of experience (7 years in the Norwegian market), passionate about building high-quality software, mentoring developers, and sharing knowledge. He has trained over 500 professionals in Architecture, EventStorming, and TDD, built and deployed more than 10 production-ready projects, led multiple development teams, and created a successful Java department from scratch.
Along the way, I’ve mentored 20+ developers and conducted 100+ technical interviews. His expertise lies in Java, but he also have experience with Kotlin, Groovy, and other programming languages. Vadzim believe that strong technical skills, continuous learning, teamwork, and knowledge-sharing are the keys to success in software development.
Marek Dominiak i a CTO of a software house, a hands-on architect, and a Trainer with 18 years of experience (15 years in Norwegian market) mainly in the Java world. He spent a lot of time mentoring developers and leading teams, with a big focus on creating sustainable solutions - systems that will last for many years. This set him on the path of learning about Software Craftsmanship, Domain-Driven Design, and code quality early on.
Marek has trained more than 500 people in modern architecture and testing. I like to share my knowledge at conferences related to software development. On some occasions I’m speaker on Software Development conferences: DevoxxPL, DevoxUK, JPrime, JDD in Krakow, Warsaw IT Days.
