David S. Batista

Hello! Welcome to my corner of the internet! :)

My name is David Batista and I’m currently based in Berlin.

I’m a machine learning engineer and software developer with a strong background in Natural Language Processing, currently working at deepset as one of the developers and maintainers of the open-source AI/LLM framework Haystack.

Before that, my path took me through academia, startups, freelancing, and established enterprises — I hold a Ph.D. focused on semantic relationship extraction and have authored multiple scientific publications.

Occasionally, I blog about Software Engineering, Machine Learning, Natural Language Processing, LLMs, RAG, and Agents.

Once in a while, I like to wander around instrumental melodies using an electric guitar. If you are curious about it you can listen to it at www.chilosopher.com
