I work at the intersection of Machine Learning, Econometrics, Statistics, and Predictive Modelling, helping clients turn real-world data into reliable analysis, meaningful insights, and models that support better decisions. My background combines Economics and hands-on data science, with published research applying statistical and econometric methods to real-world macroeconomic data, alongside production machine learning systems for forecasting, credit risk, and fraud detection. Here are some examples of what I have built: —CreditIQ: A loan default prediction system trained on 150,000 borrower records using XGBoost and ensemble modelling. It achieved an AUC-ROC of 0.844 and includes probability calibration, SHAP explainability, and business-cost threshold optimization. The system is deployed as an interactive application. —MacroSense: A U.S. economic forecasting system using Federal Reserve data to forecast GDP growth, inflation, and unemployment. The forecasting pipeline uses strict walk-forward validation across 25 years of economic data, achieving 88.9% directional accuracy for GDP forecasting. —Fraud Detection ML: An end-to-end fraud detection system built with XGBoost, MLflow, FastAPI, Docker, and monitoring. The system covers the complete workflow from model development and experiment tracking to API-based prediction and production monitoring. —Nigeria Macroeconomic Research: Research comparing traditional econometric approaches with machine learning for modelling Nigerian economic indicators, combining economic interpretation with statistical and predictive modelling. WHAT I CAN HELP YOU WITH — Machine Learning & Predictive Modelling Classification, regression, feature engineering, Random Forest, XGBoost, scikit-learn, model evaluation, explainability, and predictive modelling. — End-to-End ML & Deployment Streamlit, FastAPI, Docker, MLflow, model monitoring, and reproducible ML workflows. — Time-Series & Forecasting Economic forecasting, financial and business time series, model validation, forecasting evaluation, and leakage-free walk-forward testing. — Econometrics OLS, ARDL, time-series analysis, stationarity testing, model diagnostics, economic modelling, and quantitative research. — Statistical Analysis Descriptive statistics, exploratory data analysis, correlation analysis, hypothesis testing, regression analysis, statistical interpretation, and data-driven reporting. — Data Analysis Python, Pandas, NumPy, SQL, Excel, data cleaning, EDA, visualization, and working with messy real-world datasets. WHY WORK WITH ME? I don't believe good analysis is simply about producing a model or a table of statistical results. The goal is to understand what the data is saying, use the right methodology, validate the results properly, and communicate the findings clearly. My Economics and Econometrics background helps me understand the context behind quantitative data, while my Machine Learning experience allows me to build predictive systems when traditional approaches are not enough. Whether you need statistical analysis, econometric modelling, predictive modelling, forecasting, or an end-to-end machine learning system, I can help turn your data into something useful and defensible. — Core Skills: Machine Learning | Statistics | Econometrics | Predictive Modelling | Statistical Analysis | Data Analysis | Python | Pandas | NumPy | SQL | Excel | scikit-learn | XGBoost | Random Forest | Time Series | Forecasting | Regression | ARDL | OLS | SHAP | Fraud Detection | Credit Risk | MLflow | FastAPI | Docker | Streamlit | SPSS | Stata | R | Economic Analysis | Economics
