Case Studies

Accounts Payable Insights Part Two

Power BI

Coming soon…

The next stage of this project will extend the analytical foundation with a focus on visual design, usability, and enterprise data management concepts, including role-based access and Row-Level Security (RLS).

Accounts Payable Insights Part One

Power BI

This first part documents the end-to-end build of an invoice processing report — from defining the business questions to preparing the dataset, modelling a clean star schema, and creating core DAX measures that power the KPIs and trends.

Legal Financial & Billing

This is an interactive Power BI dashboard for tracking revenue, overdue invoices, and billing efficiency in legal services. It features financial insights, payment tracking, and revenue forecasting to support better decision-making.

Early Projects

What's for Dinner

SQL & Phyton

A fun data project where I used Python and SQL to clean a messy recipe dataset and explore what meals you can cook with the ingredients you already have. Smart, queries and everyday data magic.

Legal Business Project

Power BI

I created an interactive dashboard for this project that provides real-time insights into key legal services metrics, including total cases, open cases, and revenue. Dynamic filters and visuals help track performance and support data-driven decisions.

Fitness Data Analytics

R Programming

This project analyzes Fitbit tracker data to provide actionable insights for optimizing health and well-being. It transforms raw data into meaningful visualizations, empowering users to make data-driven decisions for a healthier lifestyle.
