I'm a Backend-focused Java Developer with 1.5+ years of experience building scalable enterprise applications. My expertise lies in developing robust REST APIs, implementing complex business logic, and integrating AI capabilities into modern applications.

Currently exploring the intersection of traditional backend development and AI, I'm passionate about creating intelligent systems that solve real-world problems. My recent work includes building AI-driven decision APIs and natural language to SQL conversion platforms.

When I'm not coding, I enjoy learning about new technologies, contributing to open-source projects, and staying updated with the latest trends in software development and artificial intelligence.
