Financial analysts and department heads were spending an exorbitant amount of time manually exporting data from isolated, legacy databases to piece together weekly Profit & Loss (P&L) reports. This tedious process not only delayed critical business decisions but also introduced high risks of human error during data entry.
I architected a self-service financial platform deployed on AWS that unified these disparate data sources into a single, cohesive analytical data warehouse. The platform provided a clean, intuitive web interface where non-technical stakeholders could dynamically filter and visualize complex financial metrics.
To achieve this, I engineered robust ETL (Extract, Transform, Load) pipelines using Python to sanitize, structure, and validate the raw financial data before it ever reached the user. I also implemented a secure API layer with strict Role-Based Access Control (RBAC) to ensure sensitive financial data was only visible to authorized personnel.
By empowering stakeholders to generate custom P&L reports independently, the platform reduced manual reporting overhead by 75%. It shifted the finance team's focus from data gathering to actual strategic analysis, accelerating the company's financial forecasting cycle.
