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

I really enjoy connecting and working with people which is why a lot of what I do is related to training & education. A part from that I like to write code, contribute a bit to open source ecosystems and I’m always eager to work on tricky challenges. Besides all the technical work and consulting I do, I try to maintain some sportive activities in order to stay healthy physically and sane mentally. The best way for me to recharge my batteries is by spending as much quality time as possible with my beloved family.


Q. Why did you select this topic for your session at Voxxed Days Cluj 2019?

I learned from my experiences in the field, that stream processing is what a lot of people and companies want to do these days and are thus currently investigating further. Oftentimes it’s very hard for them to decide where and how to start. Using an example which deals with IoT, my session tries gives some ideas and insights into how end-to-end stream processing can be implemented on top KSQL, the streaming SQL engine for Apache Kafka.


Q. Who should attend your session?

The focus of my session is to learn about KSQL, a SQL-like language for writing stream processing applications on top of Apache Kafka. Thus, everyone who is about to step into “streaming waters” and is interested to learn about a very smooth jump-start experience when it comes to building data-in-motion scenarios is very welcome and invited to participate.


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

The key take away of the session is to make the case that even without deep coding skills, stream processing isn’t necessarily as hard to start with as some folks think – with KSQL it can be easier and fun as well.


Q. Aside from speaking at Voxxed Days Cluj, what does the year review look like for you?

Given the fact that I’m only occasionally speaking at conferences, I think I did quite ok in terms of speaking engagements with 9 events in total this year. In terms of open source, I’m very happy that my Apache Kafka Connect community sink connector project became part of the official MongoDB connector for Apache Kafka earlier this year. Finally, I’m very thankful and humbled that my Apache Kafka related community efforts were recognized with the Confluent Community Catalyst award just a few weeks ago. Yes, 2019 was an exceptionally good year for me personally.>

Q. What are your plans for the next year?

My plan is to continue my speaking activities and present at a few developer related conference across Europe. Besides I have several ideas for further contributions in the Apache Kafka ecosystem and I hope I’ll manage to find the time to get some of them started and/or done. Also I have a backlog of topics to which I plan to write blog post about.
