Machine Learning Engineer

I did my Master's in Machine Learning and Cybersecurity at UPC, where I also worked as an assistant professor. At UPC I was part of the EU-funded FLAIR consortium doing research on Federated Learning and 5G edge computing.

At Amazon Science & Tech I built advanced RAG pipelines for code understanding and internal knowledge retrieval. The tools I worked on helped thousands of Amazonians onboard to complex internal systems faster, by making codebases and wikis actually searchable through AI agents. I also spent time experimenting with multi-agent architectures and designing ETL pipelines to extract information the right way, figuring out how to get reliable answers while keeping hallucinations low.

Now I work as an AI Engineer at MediaMarktSaturn, building production AI systems and multi-agent architectures for retail and service operations that automate business workflows across international markets.
