ABOUT ME
Building with purpose.
I'm a Software Engineer passionate about building backend systems and practical AI-powered applications.
My strongest foundation is in Java, Spring Boot, REST APIs, database design, authentication and backend architecture.
Alongside backend development, I'm expanding into Generative AI, LLM fundamentals, Prompt Engineering and Retrieval-Augmented Generation.
I enjoy taking an idea, turning it into a working application, debugging what breaks, and continuously improving it.
Code with curiosity.
Learn the fundamentals. Build real projects. Keep improving.
