About me
Hi, I'm an AI engineer at Amazon who ships production systems, not demos. Besides creating traditional software systems (webapps, mobile apps), I also build custom AI agents, RAG chatbots grounded in your own data, and AI automations that hold up in the real world (LangChain/LangGraph, Claude, vector DBs, Python & TypeScript). Track record: a RAG platform with citations + hallucination control, an AI code-review agent that cut review time 80%, and web apps serving 6,000+ users. Message me and let's scope your project.
My personal website is available at https://www.zsomborhorvath.tech/

This guy is a genius. We have an app up and running and wanted a bunch of features added by him. He spent his whole day working on it and turned out all features in less than 24 hours. What a beast. 10/10 would recommend and will certainly use him again.
