Hi, I'm Parnaz

About me

About me: I turn raw business data into dashboards that decision-makers actually use. I work as a Data Analyst & Business Intelligence Specialist, building reporting across sales, finance, procurement, and production. My background in Accounting lets me understand the business logic behind the numbers, not just the technical side. I'm motivated by using data to support better business and financial decisions.

What I do

What I do: 20+ interactive Power BI dashboards (SQL, DAX, Power Query, SSIS, SSAS) replacing manual Excel reporting; machine learning models in Python for sales forecasting; quantitative portfolio and risk models (mean-variance optimisation, VaR/CVaR, Sharpe, Sortino) backtested against the S&P 500; statistical research with XGBoost, SHAP and K-Means on survey data of 1,276 respondents.

Technical Skills

Technical skills: Financial Analysis & Reporting (Advanced Excel, PivotTables, Power BI, DAX, Power Query), Investment & Risk Analysis (mean-variance optimisation, VaR, CVaR, Sharpe, Sortino), Databases & Integration (SQL, T-SQL, PostgreSQL, SQL Server, SSIS, SSAS), Statistical Analysis (Python, pandas, NumPy, SciPy, statsmodels, Matplotlib, Seaborn, hypothesis testing, OLS and logistic regression, Git), Machine Learning (XGBoost, K-Means, SHAP)
