Portfolio
Dynamic models, automation, and dashboards built with advanced Excel techniques.

📖 Advanced Excel Portfolio – Financial Modelling, Analysis & Automation
An end-to-end Excel portfolio showcasing how I transform Excel from a basic spreadsheet tool into a powerful engine for financial forecasting, variance analysis, and process automation.
💡 What makes this project different?
I combine finance-specific use cases (budgeting, forecasting, variance, and sensitivity analysis) with advanced Excel techniques (XLOOKUP, FORECAST.ETS, Solver, Power Query, LAMBDA) to build error-resistant models, automated workflows, and interactive dashboards — demonstrating both technical mastery and business impact.
Featured Content
- 📈 Financial Forecasting — using FORECAST.ETS, Solver, regression & scenario planning
 - 📊 Variance Analysis — budget vs. actuals with variance drivers across accounts & categories
 - 🛠️ Process Automation — Power Query, PivotTables, error-proof templates, macros
 - 👥 Sensitivity & Scenario Analysis — What-If, Goal Seek, Scenario Manager, Data Tables
 - 🎨 Dashboards & Visualization — interactive charts, KPIs, maps, sparklines, advanced formatting
 
Key Insights
- Advanced Excel enables finance teams to forecast more accurately using statistical models.
 - Variance analysis highlights key revenue/cost deviations for proactive decision-making.
 - Sensitivity tools (Goal Seek, Data Tables, Solver) support strategic planning under uncertainty.
 - Automation with Power Query and macros reduces reporting time and improves reliability.
 - Dashboards make complex trends accessible to decision-makers at a glance.
 
Outcome
Delivered a comprehensive Excel portfolio that:
- Demonstrates advanced modelling and forecasting for finance
 - Identifies variance drivers and high-impact scenarios
 - Bridges finance workflows with automation & efficiency gains
 - Provides decision-ready dashboards for executives and analysts
