About Me
Senior Software Engineer | Backend Engineering • AI Systems • RAG • Data Engineering
I'm a Senior Software Engineer with 4+ years of experience building scalable backend systems using Python, Django, Django REST Framework, and FastAPI. I specialize in designing REST APIs, distributed data pipelines, backend architecture, and AI-powered applications.
My recent work focuses on Retrieval-Augmented Generation (RAG), AI Agents, LangGraph workflows, semantic search, vector embeddings, document processing, and enterprise AI systems. I enjoy building reliable, production-ready software with clean architecture and long-term maintainability.
