Hello!

I'm Joumen Harzli, a Freelance AWS Cloud & AI Consultant, based in Paris, France.

I help companies design, build and ship modern production-ready AI applications, built on scalable AWS cloud and microservices architectures.

My expertise spans Cloud & AWS, Large Language Models (LLMs), Big Data, and large-scale distributed systems — with a strong focus on building things that are ready for production, not just proof-of-concept.

Whether you're looking to build a scalable cloud product, integrate LLMs into your product, or unlock the power of AI in your business, I provide tailored solutions that meet your unique needs.
