Hi, I'm Nuno

Quantitative Finance & Data Science profile focused on applying mathematics, statistics, programming and AI to problems in finance, banking, risk analytics and derivatives pricing.

Focus Areas

  • Quantitative Finance
  • Risk & Banking Analytics
  • Data Science / Machine Learning
  • Python for analysis, modelling and prototyping
  • C++ for numerical methods and performance
  • SQL, Excel and Power BI for reporting
  • Applied AI / LLMs in finance

Project Roadmap

Status Project Focus
Completed Regime-Switching Local-Volatility Option Pricing (MSc thesis) Two-regime local-volatility PDE, finite differences, convergence, American puts, empirical validation and Power BI
In progress Credit Risk Model Validation PD modelling, challenger models, discrimination, calibration, stability and simplified IFRS 9 ECL
Next Option Pricing: Python vs C++ Black-Scholes, Monte Carlo, numerical methods and performance comparison
Planned Market Risk: VaR & Expected Shortfall Historical simulation, Monte Carlo, backtesting and risk reporting
Planned Volatility Forecasting Time series, GARCH and regime-switching models
Planned Financial RAG Assistant LLMs, embeddings and financial document analysis

Portfolio Philosophy

The goal of this portfolio is to build practical, well-documented projects that connect:

Finance problem
→ data
→ modelling
→ implementation
→ evaluation
→ interpretation
→ communication

Python is used mainly for research, analysis and modelling. C++ is used where numerical performance matters, especially in quant finance.
