About the trainers

Vadzim Prudnikau
Architect / Team Lead / Senior Developer – 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. I’ve trained over 600 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. – My expertise lies in Java, but I also have experience with Kotlin, Groovy, and other programming languages. I believe that strong technical skills, continuous learning, teamwork, and knowledge-sharing are the keys to success in software development.

Marek Dominiak
Owner of a Software Company / Architect / Lead Developer – I’m 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. I’ve 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 me on the path of learning about Software Craftsmanship, Domain-Driven Design, and code quality early on. I’ve completed many small and large projects that run in production, interviewed developers, handled communication with customers, helped design Architecture for entire systems and delivered them, and introduced many technologies proven in production. I’ve trained more than 600 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: NDC Oslo, Javazone, DevoxxPL, DevoxUK, JPrime, JDD, Warsaw IT Days,…)

Quotes from previous course participants

“The course is packed with real-life examples by two battle hardened architects that help you to understand the topics better.”

“What made this course exceptional was its practicality; it equipped us with actionable knowledge that can be applied in real projects.”

“The course was very well structured and Marek and Vadzim were skilled at running a course packed with interesting content, all the while making sure we had time to discuss and talk about the subject matter at hand.”

“Marek and Vadzim are excellent communicators and presenters. They used clear and understandable language to describe complex concepts with code, slides and real-life examples. They included all the participants in the discussion and team challenges to test our knowledge.”

“I signed up for this course with three clear goals in mind: to learn new concepts for effective architecture, deepen my understanding of the architectural principles I already apply, and identify areas where I need to grow further. By the end of the course, I not only achieved all these
objectives but also gained insights I hadn’t expected.”
