πŸ“ˆ Senior FP&A & Finance Analytics | Financial Modeling | Forecasting | Data-driven Finance | Python | SQL | Power BI

Senior FP&A and Finance Analytics professional with 15+ years of experience in financial modeling, reporting, forecasting and finance transformation.

I design data-driven finance solutions by translating finance requirements into scalable analytical workflows using Python, SQL, Excel and BI tools.

My work sits at the intersection of Finance, Data and Analytics, building integrated FP&A environments that combine financial modeling, data pipelines, statistical forecasting and executive dashboards.

Recent work includes the design of an end-to-end Finance Analytics Platform simulating a modern finance data stack:

Financial Modeling β†’ Data Warehouse β†’ Python Automation β†’ Forecasting β†’ BI Dashboards.

πŸš€ Featured Projects

πŸ“Š Digital Finance Forecasting & Analytics Platform

End-to-end Finance Data Stack that integrates financial modeling, data engineering, statistical forecasting, and business intelligence into a unified analytics platform.

Key components:

β€’ Integrated IFRS 3-Statement financial model (Excel)
β€’ Financial Data Warehouse (PostgreSQL Star Schema)
β€’ Python automation pipeline for financial reporting
β€’ Statistical forecasting models (SARIMA) and scenario simulation
β€’ Power BI executive dashboards

The project demonstrates how modern finance teams can move from spreadsheet-based reporting to scalable analytics-driven FP&A systems.

πŸ“ˆ Volatility Forecasting with HAR-Type Models

Master’s thesis in Finance (University of Minho) investigating financial market volatility forecasting using HAR-type econometric models implemented in R.

The research evaluates 16 variations of HAR-based models applied to FTSE-100 realized volatility, incorporating jumps, signed jumps, realized semivariance, and leverage effects, with model performance assessed through multiple loss functions and statistical validation techniques.

πŸ’°Bankruptcy Prediction

Predicting corporate financial distress using machine learning and financial data analysis. Implements Random Forest, XGBoost, SVM, and more to classify bankrupt vs. non-bankrupt companies.

🏦Bank Customer Churn Prediction

Predicting customer churn in the banking sector using machine learning and customer data analysis. Models compared include Random Forest, XGBoost, and SVM, with an emphasis on optimizing recall over accuracy for better retention strategies.

πŸ“‘Telecom Customer Churn Prediction

Predicting customer churn in the telecom industry using machine learning and feature selection techniques. Implements Random Forest, XGBoost, and CatBoost, with data balancing (SMOTE, undersampling) and hyperparameter tuning to maximize recall and identify at-risk customers.

πŸš€Provento-Manager

A web application for startup acceleration and mentorship management.
