2️⃣0️⃣2️⃣5️⃣Spring Boot 2025 Rewind ⏪🍃

As a passionate advocate for cloud-native Java development, I’ve been actively producing educational content focused on Spring and Spring Boot, key components of the VMware Tanzu ecosystem. Through a series of articles and video tutorials published on platforms like Udemy and YouTube, I’ve helped hundreds of developers understand and implement Spring-based solutions in modern enterprise environments. My contributions aim to bridge the gap between Spring technologies and the real-world constraints teams face in production: platform engineering, Kubernetes readiness, resilience, security, and observability.

Looking back on 2025, my focus has been consistent: make Spring knowledge practical and shippable. From mastering the fundamentals (Core, MVC, Data, Security) to embracing modern architecture patterns (cloud-native, event-driven, reactive where it fits), I’ve shared hands-on guidance that developers can apply immediately—whether they’re building internal APIs, migrating legacy applications, or scaling services in the cloud. This year rewind is a snapshot of what I learned, what I taught, and what I saw teams investing in—so we can start 2026 with clearer priorities, stronger engineering habits, and Spring applications that are easier to run, evolve, and trust.
