About me
I am a full stack developer and AI engineer with four plus years shipping software to production, not just demos. Expertise covers LLM integration, AI agents, and RAG systems using LangChain, LangGraph, and Claude and OpenAI APIs, backed by React, Next.js, Node.js, and PostgreSQL.
My services include RAG chatbots on your own data, AI agents that call tools and take real actions, full stack apps with AI built in, and computer vision or data extraction pipelines.
I am available 24/7 and happy to set up a quick Zoom call early on so we can walk through your requirements and start drafting.
