Jarek Ratajski – Speaker interview

Jarek Ratajski is a Java Developer since 1999. I love programming since my first line of code I did on the C64 in Basic. I have 15 Years experience developing JEE software working for various companies and projects. Currently I am working for CSS Versicherung in Luzern. I am Java developer during the days and Scala/ScalaJS at nights. I like to present my experience in public – so far speaked at conferences such as Devoxx, Voxxed Days, JUGs, Geecon, JdayLviv etc. I like to do shows – presenting the things just as they work – with live coding, demos and hacking.

 

Talk: DROP DATABASE – galactic story

 

Q. Tell us a bit about yourself. What are your hobbies and interests?

I am probably typical software engineer -and I was passionate on programming even before I got the first computer.

As for other hobbies for sure I love to read a lot about the past – history and when the weather is fine I do mountain hiking in the alps.

 

Q. Why did you select this topic for your session at Voxxed Days Cluj-Napoca 2017? 

I hate cargo cults in software engineering – so more or less all my sessions are about question “why do we develop systems this way”? Is is really efficient, are there any alternatives?
This session is about databases? Do we really need them ? Always ?

 

Q. Who should attend your session? 

Software developers, architects that want see something completely different in the area of data persistence.

 

Q. What are the key things attendees will take away from your session? 

– databases are really bad at storing data,

– they were once needed – but this time is gone,

– CQRS + Event sourcing – beats databases in terms of programming efficiency and performance,

– there are easy ways to do Even Sourcing without complicated frameworks,

– Java has more power than you may possibly know.

 

Q. Aside from speaking at Voxxed Days Cluj-Napoca 2017, what is the year review look like for you?

Attended tons of sessions at multiple conferences:

impressions: when it comes to software development – we are slowly starting to make it right… but there is still a lot to do.

 

Q. What are your plans for the next year?

Haskell, Idris – and way more mountain hiking.
