What I'm looking for

I'm looking to build practical NLP, LLM, and machine learning systems, combining research-driven experimentation with product-focused engineering and measurable real-world outcomes.

I've built NLP and conversational AI systems at TU Delft and Volentis.ai, including a hybrid value-extraction tool that transforms documents into structured datasets and MCP-based HRIS integrations that reduced manual queries by 50%.

My work spans fine-tuning multi-label NLP classifiers, LLM components, REST APIs, and MongoDB optimization. Previously, at BioSim Lab NTUA, I designed CNN architectures for Covid-19 cough detection, improving AUC by 13% and presenting the research at IEEE EMBS BHI 2024.
