What I'm looking for

I seek data-science roles applying ML/DL to real-world problems, favoring collaborative, research-driven teams where I can build robust, explainable models and impact product or research decisions.

I am a data scientist with advanced degrees in Information Systems (Big Data & Analytics) and Pure Mathematics, combining rigorous mathematical training with practical machine-learning and deep-learning expertise. I have developed production-style models including a relational GCN on a large heterogeneous biomedical knowledge graph and deep-learning pipelines for medical imaging, delivering top-ranked novel predictions and validated model outputs.

I bring hands-on experience in NLP, graph analytics, distributed data processing, and statistical modeling, plus applied consulting on agricultural biomass forecasting and uncertainty quantification. I am committed to building robust, explainable models and providing data-driven recommendations that inform strategic decisions.
