What I'm looking for

I’m looking for remote contract work evaluating and writing data science and statistics problems.

At the Ministry of Transport and Logistics, I built a multilingual document intelligence system combining OCR and hybrid semantic retrieval for Arabic and French documents. Retrieval accuracy was above 76%, with latency under five seconds.

At the High Commission for Planning, I diagnosed missing values in 2014 census files and documented a protocol comparing five imputation methods under controlled missingness scenarios. I also detected and fixed an information-leakage risk, then evaluated results with point and distribution metrics.

On a Lending Club project, I led modelling on approximately 2.9 million loans, comparing six models and applying Optuna tuning, calibration, and survival analysis. With two teammates, I delivered a Streamlit dashboard, explainability, and a Fairlearn fairness audit.

My work also includes an end-to-end telecom churn pipeline and a privacy-preserving federated learning system for medical AI. I’m looking for remote contract work evaluating and writing data science and statistics problems.
