AI Engineer & Backend Developer As an AI Engineer and Backend Developer, I specialize in building **production-ready AI applications, scalable APIs, and intelligent backend systems** using Python, Django, FastAPI, and modern Generative AI technologies. I have developed LLM-powered applications, RAG pipelines, AI chatbots, document Q&A systems, semantic search solutions, and AI-driven APIs. My experience includes designing complete AI workflows covering document ingestion, text processing, chunking, embeddings, vector search, retrieval, prompt engineering, and LLM-based response generation. On the backend, I build robust Django, Django REST Framework, and FastAPI applications with clean architecture, authentication, validation, pagination, filtering, exception handling, database integration, and Swagger/OpenAPI documentation. I work extensively with PostgreSQL, MySQL, SQLite, SQLAlchemy, and Django ORM, including database schema design, relationships, query optimization, and data management. For deployment and scalability, I use Docker and Docker Compose to containerize applications and create consistent development and production environments. I also work with Linux, Git, GitHub, Uvicorn/Gunicorn, environment configuration, and API deployment workflows. Key Achievements • Built AI-powered RAG and document Q&A applications. • Developed scalable REST APIs using FastAPI and Django REST Framework. • Integrated LLMs, embeddings, vector search, and third-party AI APIs. • Designed and optimized PostgreSQL/MySQL database architectures. • Dockerized AI and backend applications for reliable deployment. • Implemented semantic search and relevance-focused retrieval systems. • Developed ML/AI inference APIs for real-world applications. • Created well-documented and maintainable backend architectures. Core Expertise Python | Django | DRF | FastAPI | Generative AI | LLMs | RAG | LangChain | Hugging Face | NLP | PostgreSQL | MySQL | REST APIs |
