Krakow, Poland, 11 - 13 June 2025
Jacek Marmuszewski - DevSecOps with over ten years of experience building and managing cloud infrastructure. He worked for companies like Sabre and Oracle on mission-critical systems. He also had his share in startups, where, as an early joiner, he promoted DevOps culture and advocated cloud-native architecture.
Recently, he co-founded Let’s Go DevOps, a company that helps others design, build, and maintain cloud-native applications and infrastructure. He’s a big fan of cloud transformation and helps others leverage its full potential by choosing the right components for the job.
Old, complicated, and boring—those might be the first words that come to mind when discussing relational databases. However, despite these perceptions, everyone continues to use them. You might argue that "an ORM will handle all the heavy lifting," but what do you do when it doesn’t?

- How are indexes structured?
- Why types are important?
- What is database normalization?
- How is data stored on physical volumes (MVCC)?
- How does the replication work?
- Why do we need WAL logs?
