What I'm looking for

I’m looking for a Python backend role where I can build FastAPI/Django APIs, ship Dockerized services, and integrate ML features when it adds value—working with a team that values clean architecture and measurable outcomes.

I build REST APIs with Python—shipping FastAPI and Django REST Framework services that are clean, testable, and easy to deploy with Docker. I also enjoy blending ML into backend workflows, from model integration to experiment tracking and explainability.

Recently, I built an Early Burnout Detection system with XGBoost, added a FastAPI /predict endpoint, Dockerized the stack, and delivered SMOTE, SHAP, and MLflow tracking (Weighted F1 ~0.849, ROC-AUC ~0.787). I’ve also developed a Django Online Shop API across multiple view patterns and deployed a Heart Disease Prediction FastAPI service with Streamlit and docker-compose.
