What I'm looking for

I'm interested in building reliable, user-centered AI products.

At Fiverr, I deliver Python machine-learning and deep-learning solutions for text, image, and structured data, then integrate inference into FastAPI, Flask, and Streamlit applications.

In published research, I combined BioGPT with model predictions and SHAP evidence to generate clinical explanations, and built a DistilBERT sentiment-analysis pipeline that reported 91% accuracy and 89.8% macro-F1. I’m interested in building reliable, user-centered AI products.
