Lukáš Kožušník

I'm a self-taught backend developer with 4+ years of experience in Python, with a growing focus on AI and LLM‑powered applications. I discovered programming through my passion for logic and mathematics, which naturally led me to explore real‑world problem solving through code.

Currently, I'm a backend / LLM developer at EDIMA, where I develop the AI‑powered backend for Edmund—a digital assistant for industrial automation. I build LLM‑based agents with RAG pipelines, handle data integration, and manage backend architecture using FastAPI, Django, LangChain, and LangGraph.

Previously, I worked as an AI specialist at 24 VISION, designing and deploying neural networks for computer vision tasks, and did a backend contract at Presentie, integrating OpenAI DALL‑E for automated image generation. I've also built personal projects like a crypto trading bot and various APIs.

I studied Computer Science at VŠB – Technical University of Ostrava for two years before choosing to move from theory to practice, focusing on building real‑world experience. I'm based in Frýdek‑Místek, Czech Republic.
