BrabantJUG
The BrabantJUG meetup Den Bosch takes place on June 23rd, hosted by HighTech Innovators. We’re proud to open our doors for this BrabantJUG meetup in Den Bosch, with two great speakers: Rijo Sam and Jessica Siewert will share their knowledge on Java architecture and team collaboration.
Attendance is free. Register via the BrabantJUG @ HighTech Innovators event page on Meetup to reserve your spot.

The Problem: Modern Java apps often get stuck in their frameworks. Tools like Spring Boot and Quarkus speed things up, but they come with hidden costs such as vendor lock-in, heavy dependencies, and rigid architecture. So what happens when your app outgrows the framework, or something better comes along?
The Solution: This talk introduces a layered approach to Java development, isolating framework dependencies while keeping core logic pure with Java and Jakarta EE. Through examples, you’ll see:
Trade-Offs: Yes, this demands more upfront effort, including writing custom persistence layers, rigorous tests, and meticulous documentation. But the payoff is code that’s adaptable, testable, and maintainable across frameworks, teams, and decades.
Key Takeaways:
About Rijo
Rijo is a software developer and public speaker based in the Netherlands. He has extensive experience building applications in the payments and credit sector of the banking domain. Outside of work, he’s usually on his bike trying to beat his cycling buddies.
Every now and then, everyone joins a new team, or someone new joins theirs. More often than not, cooperation doesn’t go seamlessly straight away. Sometimes it evens out along the way. But in many cases, it doesn’t. Ways of working can differ. Something one person values highly may not be valued at all by another, creating conflict. You criticise or get criticised, and things get uncomfortable. Teams split into “camps”, or one person never agrees with the others. Team members feel stepped over, pushed aside or misunderstood. If this goes on too long, people start to feel generally disrespected and demotivated. Then there are cases where one member feels another isn’t qualified, or is just a bully. This goes beyond forming and storming — this becomes a team-wide problem.
In this talk you’ll see you’re not the only one experiencing these challenges. You’ll hear experiences on solving these kinds of cases (or not!), get an idea of how others deal with it, and learn what your options are if you ever find yourself in the weeds (again). Either way, you’ll probably be surprised by yourself or your teammate in one way or another.

Even when she isn’t the scrum master, she takes pride in helping teams through the transition from old members to an all-new team. She also enjoys working with neighbouring teams to give people in the Netherlands a better experience around the major upgrade of the Dutch energy network. She likes to share her experiences in both engineering and working relationships with her fellow crafts(wo)men.
