Vencel David Koczka Data Scientist · Software Engineer

Budapest, Hungary

Building scalable AI and data-driven solutions — from RAG pipelines to intelligent systems.

About Me

I am a Data Scientist with a Master's degree from Uppsala University, specializing in large language model applications and retrieval-augmented generation (RAG). This expertise was the focus of my master's thesis and was applied professionally in my role at Hypertype. My background includes developing predictive analytics at Ericsson, automating financial pipelines at EPIC InnoLabs, and building scalable systems with .NET, Angular, and Docker. Passionate about bridging research and application, I thrive at the intersection of machine learning, software engineering, and innovative AI solutions.
