Tamas Csakvari

I am a Data Scientist specializing in building and fine-tuning Large Language Models (LLMs). My focus is on using advanced AI to solve complex and meaningful problems.

With a background combining quantitative analysis from engineering and economics, I bring a unique and rigorous approach to my work. I am fluent in English and German and am excited to connect with teams building impactful technology in Europe.
