👨‍💻 About Me

🚀 Java Backend Engineer with a strong foundation in Data Structures & Algorithms, focused on building distributed and highly scalable backend systems using the Java & Spring ecosystem.

⚙️ I specialize in designing and developing high-performance APIs and microservices using Spring Boot, Spring MVC, Spring Security, Spring Batch, and Spring Reactive (WebFlux) — following industry-standard SDLC practices and MVC-based architecture.

🗄️ My experience spans distributed system components and data platforms including SQL, MongoDB, Redis (caching), and Apache Kafka for event-driven architectures — with observability via ELK, Prometheus, and Grafana in production systems.

☁️ I work with Docker, Kubernetes, and cloud-native deployments on AWS (EC2, EKS), support CI/CD pipelines with Jenkins, and follow Git-based workflows across Git, GitHub, and Bitbucket. I also have hands-on experience with MCP servers and a solid functional understanding of DevOps practices.

🤖 Beyond traditional backend engineering, I actively explore AI-driven architectures — including Agentic AI, RAG (Retrieval-Augmented Generation), and vector databases — to build intelligent, data-aware applications that integrate modern AI capabilities with scalable backend infrastructure.

🌐 Continuously expanding expertise across cloud-native systems, distributed architectures, and emerging technologies such as Web3 and AI-powered platforms.
