About Me

I am a self-taught software engineer driven by a deep curiosity for how complex systems work. My journey began with simple scripts and evolved into architecting cloud-native microservices for enterprise environments.

Unlike many who focus solely on frontend trends, I prioritize the robustness of the backend. I believe that a great application is built on a foundation of secure APIs, efficient databases, and scalable infrastructure.

Currently, I am exploring the intersection of AI Engineering and traditional software development, building RAG systems that bridge the gap between LLMs and structured enterprise data.
