Juan Garassino — AI Engineer
Juan Garassino is an AI engineer based in Berlin, Germany, specializing in
multi-agent systems, large language model (LLM) applications, and generative AI. He designs
and ships production AI systems and teaches machine learning, with a background that bridges
architecture (Universidad de Buenos Aires) and applied AI/ML engineering.
What Juan does
Juan builds multi-agent orchestration systems (LangGraph, LlamaIndex, and custom hand-rolled
agent loops), retrieval-augmented generation (RAG) pipelines, fine-tuned and quantized LLMs
(LoRA/QLoRA, PEFT, RLHF with GRPO/PPO/DPO), and generative models (diffusion, GANs). He works
across the full stack — FastAPI backends, Docker/Kubernetes, and GCP, AWS, and Azure — and has
a research interest in LLM interpretability and AI red-team security.
