Hi, I'm Sonia, a Web Application Developer, AI Engineer, and LLM Specialist. I build intelligent, production-ready applications using GPT, LangChain, and RAG (Retrieval-Augmented Generation) pipelines. I help businesses turn their own data into smart AI systems using Python, React, and Node.js.
I design solutions grounded in your actual business data — making them more accurate and genuinely useful, not generic AI outputs.
From custom AI chatbots and RAG-based knowledge systems to full stack apps and API integrations, I deliver clean, well-documented, and reliable code — every time.
