Hello, I'm

RAJ
RIBADIYA

Backend & Applied AI Engineer

I'm a backend-focused Full-Stack Engineer passionate about building scalable, reliable, and high-performance systems. I enjoy designing efficient architectures, solving complex engineering problems, and understanding how systems perform under real-world constraints.

Alongside backend engineering and distributed systems, I build applied AI applications using techniques such as Retrieval-Augmented Generation (RAG), vector search, embeddings, and intelligent AI-driven workflows. I'm continuously exploring ways to combine solid software engineering with AI to build practical, production-ready solutions.
