About Me

I'm a Computer Science student at Air University with a passion for building backend systems that are both scalable and intelligent. My journey into software engineering started with curiosity about how systems communicate — and quickly evolved into building real-time platforms, AI-powered tools, and production-grade APIs.

What sets me apart is my focus on AI/RAG integration at a practical level. I've built systems that use LLama 3.2 with vector databases for retrieval-augmented generation, automated code review bots with Gemini AI, and crypto trading assistants — all while maintaining clean architecture and fault-tolerant design.

As a member of the Microsoft Learn Student Ambassadors program, I actively contribute to the developer community through bootcamps and programming competitions, bridging the gap between learning and building.
