About

I build AI applications that solve real problems. My current focus is on developing production-ready AI systems—RAG pipelines, LLM-powered applications, AI agents, and intelligent automation. I work across the full stack of AI engineering: from designing prompts and managing conversation memory to deploying scalable APIs with FastAPI. I'm writing "Zero to AI Engineer: Python Foundations"—a comprehensive 110-chapter guide that takes developers from Python fundamentals to building production AI applications. The book covers everything from core programming concepts to LangChain, LangGraph, PydanticAI, RAG systems, and deployment with Docker and CI/CD. My background in frontend development (React, Next.js) gives me a unique perspective on building AI applications with exceptional user experiences. I understand both sides: the elegant interface and the intelligent backend. What I work with: → AI/LLM: OpenAI API, LangChain, LangGraph, PydanticAI, RAG, Vector Databases (ChromaDB) → Backend: Python, FastAPI, SQLAlchemy, Pydantic → Frontend: React, Next.js, TypeScript → DevOps: Docker, GitHub Actions, Railway/Render Currently building AI applications and writing about AI engineering. Let's connect if you're working on AI applications or interested in the intersection of AI and developer experience.
