Java Backend Engineer | Spring Boot | Microservices | Kafka | Cloud-Native Systems

Hey! I'm a Software Engineer passionate about building scalable, reliable, and distributed systems. I work primarily with Java, Spring Boot, Microservices, and event-driven architectures. I enjoy exploring system design, distributed messaging, cloud technologies, and performance optimization. I'm particularly interested in: - Backend Engineering with Java & Spring Boot - Microservices and Event-Driven Architecture - Apache Kafka and Distributed Systems - Kubernetes, Docker & Cloud Technologies - System Design and Software Architecture - Exploring AI-powered developer tools I use this space to share what I learn, document real-world engineering challenges, and break down complex technical concepts into practical insights. Always learning. Always building. 🚀
