My new video course is now live on #Udemy 🎊. Apache Kafka for Event-Driven Spring Boot Microservices. I like how my year started.🥳. #ApacheKafka #SpringBoot.

My 𝗡𝗘𝗪 video course is now live! 🥳. This course teaches how to use 𝗞𝗮𝗳𝗸𝗮 𝗖𝗼𝗻𝗻𝗲𝗰𝘁 to move data between Kafka and external systems like relational databases. Course link:.

Just because it’s called an integration test doesn’t mean it has to start the whole app. You can load only a slice of your Spring context. You can mock the rest. You’re still testing how components talk to each other. But you’re doing it faster and cleaner.

I love hearing good news from people who took my video courses 😊

One more week and I should have my new video course published. This one is about Apache Kafka Connect, which helps to stream or move data from almost any data source to almost any other destination system—like a database, a file, or cloud storage.

And as I swiped through the ad slider, I saw 4 more of my courses there 🥳🎊😍.

I was scrolling through my Instagram feed and saw an ad by Udemy. I clicked on it — turns out it’s my video course that’s being advertised 🥳. Feels really good to see Udemy promoting my course 😊. #microservices

Knowing how to test your Java application is not only needed to get a job. It's also what helps you keep it!. Tests are my safety net every time I push new code. They give me confidence and peace of mind. #Testing.

As much as I love unit testing and mocking, I never feel fully confident unless I also write an integration test 🤷🏻‍♂️. I need to see it working end to end. Is it my anxiety talking? Or do you feel the same way? 😅. #Testing #UnitTesting.

It is so cool how Kafka Connect can move/stream data from pretty much any source to almost any destination. #ApacheKafka #KafkaConnect.

Working on new video lessons for my Apache Kafka video course But this week it’s been tough. This little creature comes every few minutes and asks for hugs 😅

I’m working on more every day, and the list keeps growing. Hope you find these new lessons helpful!.

Added a lot of new video lessons to my Testing Java Applications video course on Udemy(. These lessons focus on 𝘁𝗲𝘀𝘁𝗶𝗻𝗴 𝗥𝗘𝗦𝗧𝗳𝘂𝗹 𝗪𝗲𝗯 𝗦𝗲𝗿𝘃𝗶𝗰𝗲𝘀 𝘄𝗶𝘁𝗵 𝗥𝗘𝗦𝗧 𝗔𝘀𝘀𝘂𝗿𝗲𝗱.

I've added new video lessons to my Reactive Spring Boot applications course. These lessons teach how to implement Server-Sent Events in your Reactive Spring Boot application and broadcast them to multiple JavaScript clients.

OAuth Flow for Mobile applications and JavaScript clients. Video lessons are here:

The process of building something is always more interesting than the actual end product. The same goes for your life.

The more you learn, the more you earn. The same applies to software development 🙂.

Coding is like writing:.1. Start simple. 2. Embrace mistakes. 3. Keep refining. Remember, every line of code you write is a small, satisfying victory.

Every time I publish a new video course, I spend the next couple of days fearing I’ll be hit by a ton of rotten tomatoes. 😅.

Adding new video lessons that explain how to implement Server-Sent Events (SSE) in a Reactive Spring WebFlux application.
