Fernando Barščevičius

Machine Learning Engineer | Data Scientist with 8 years of experience in machine learning and advanced analytics. As a generalist, I've tackled a range of challenges, including clustering, regression, classification, and recommender systems. My expertise spans from classical NLP to modern AI applications, having recently worked on AI Agent development, RAG systems, and LLM fine-tuning projects.

At C6 Bank, I led a team of 7 data scientists to develop models that significantly improved CRM strategies. At Nubank, I improved NLP models that enhanced customer support operations by optimizing auto-reply and routing systems for in-app chat support and email queries. My work blends technical expertise with business objectives, resulting in enhanced product offerings and market success.

I thrive in rapidly evolving environments, driven by a commitment to lifelong learning and collaboration. My problem-solving capabilities and effective communication skills enable me to translate complex data insights into strategic business actions.
