I am a Full Stack AI Engineer with 5 years of experience building intelligent, production-ready web apps — from AI Agents, LLM integrations and RAG pipelines to scalable API backends and clean React frontends. I work with Python, FastAPI, LangChain, LangGraph and LLMs — OpenAI, Claude, Gemini — to ship AI features that actually work in production. Backend architecture, vector search, real-time systems and cloud deployment are my core. Frontend side covers React, Next.js and TypeScript. Also experienced in Web3 and decentralized app development. Clean code. Scalable systems. Real results.
