About this Gig

Do you need financial insights to guide smarter decisions? I will help you analyze your financial data, build models, and create forecasts to evaluate, risks, returns, and investment strategies.


With my background in Applied Mathematics (Statistics & Computational Math) and experience in Portfolio Optimization (Markowitz Theory), I specialize in transforming raw financial data into clear, data-driven insights.


What I offer:


  • Financial data cleaning & preprocessing (Excel, CSV, SQL)
  • Portfolio optimization (Markowitz, Efficient Frontier, CAPM, Sharpe Ratio)
  • Time series forecasting (ARIMA, Prophet, Exponential Smoothing)
  • Risk analysis (VaR, volatility, scenario simulation)
  • Interactive dashboards (Power BI, Google Data Studio, Tableau)
  • Professional reports with visualizations and recommendations


Technologies I use:

  • Python (Pandas, Numpy, Matplolib, Scikit-learn, Tensorflow/Keras, PyPortfolioOpt, Riskfolio)
  • R (forecast, tidyverse, ggplot2, Shiny, PortfolioAnalytics)
  • Excel (financial modeling, VBA, Solver)
