I build LLM systems that actually work in production. Based in Berlin, working with clients worldwide.
christo@9592.techWhat I do
I build software across the stack: backends, mobile apps, AI systems, and the infrastructure to make them work in production.
Most of my work involves LLMs. Conversational agents, retrieval systems, data extraction. But I focus on whatever creates real value for you, your users, or your audience.
