🌼 Reflecting on a Year of Spring-Fueled Content Creation

As summer sets a calmer rhythm, it’s the perfect season to pause and reflect. For developers who thrive on sharing knowledge, it’s a chance to look back at how we've contributed to the tech community—and in my case, how Spring Framework has shaped every piece of that journey.

Over the past year, I’ve dedicated my content creation to helping others build production-grade Spring Boot applications, prepare for Spring certification, and master backend development within the Java ecosystem. From in-depth tutorials and open-source tooling to video walkthroughs and certification prep, every resource I’ve created is rooted in Spring.

Here’s a look at my Spring-focused contributions across platforms—from Foojay articles to my personal blog, Udemy course, and YouTube tutorials—all designed to support developers and architects navigating the ever-evolving Spring landscape.

🎤 Events & Speaking — Lighting Up the Spring Stage

One of the highlights of this year was stepping out from behind the keyboard to present in person at Spring Meetup Paris, just steps from the Opera. In front of a packed room of around 100 Spring enthusiasts, I shared a live talk focused on pushing performance boundaries with Spring Batch and GraalVM Native Image—and why this combo can be a powerful lever for FinOps optimization.

The session (delivered in French, with an English version available) was titled:

FR: Des Spring Batchs plus rapides que Flash (et plus économiques) avec GraalVM Native Image ⚡ EN: Spring Batch Faster than Flash ⚡ with Spring Native and GraalVM to save FinOps costs

🗓️ Date: March 2025

📍 Location: Spring Meetup Paris, Opera avenue

🌐 Online Communities, Tools & Contributions

Beyond articles and talks, a key part of my mission has been giving back to the Spring community through open-source projects and community support. Whether it's maintaining sample repositories, helping fellow developers debug tricky Spring configs, or contributing solutions around Kafka and GraalVM, these efforts extend the conversation beyond my own platforms.

Here’s how I've stayed actively involved this past year:

🔹 GitHub Repositories

On GitHub, I maintain a growing collection of Spring-focused demo projects. These include working examples for CloudEvents, Kafka Streams, Spring Native integrations, JPA mappings, and security practices—each crafted to be educational, reproducible, and ready-to-use.
