Featured Projects

Real Problems.
Real Solutions.

Every project tells a story of a data challenge identified, investigated and solved. Here are some of the most impactful.

🏫
SQL Databricks Power BI Excel Education
School Assessment Analysis — TMET
End-to-end analysis of primary school assessment data for a Multi Academy Trust. Built a full Medallion Architecture pipeline in Azure Databricks, a 3-page Power BI dashboard and an interactive Excel workbook — all revealing critical pupil attainment gaps across year groups and demographic categories.
Year 4 Pupil Premium pupils recorded 0% Above Age Related Expectations — a finding that directly informed leadership intervention strategy.
 📊
Power BI DAX Dynamics 365 Mailchimp GA4
Sales & Marketing Dashboard — GTC Group
Designed and built a 4-page Power BI dashboard connecting 5 data sources — Dynamics 365, Mailchimp, Metricool, Google Analytics and Excel templates — into one unified leadership view. Built custom DAX measures, dynamic date filtering and multi-currency pipeline tracking.
The dashboard became so embedded in operations that its absence during a leave period immediately disrupted weekly leadership meetings — proving its business-critical value.
 🧠
Databricks SQL Power BI Excel Mental Health
Teen Mental Wellness & Behaviour Analytics
End-to-end analysis of behavioural habits, AI usage patterns and emotional wellbeing across 1,000 simulated teen records. Built a full Medallion Architecture pipeline in Azure Databricks, a 3-page Power BI dashboard and a 10-slide published analytical report with WHO and RAND references.
AI usage spiked 28% on Wednesdays — suggesting teens lean on AI at academic pressure points, not just for leisure. A finding that challenges the "just restrict AI" narrative.
 💰
PySpark Python Databricks Power BI DAX
The Profit Paradox — Financial Sales Analysis
End-to-end financial sales analysis across 700 transactions, 5 segments, 5 countries and 6 products. Built a full Medallion Architecture pipeline in Azure Databricks using PySpark and Python, 5 Gold aggregation tables, Python visualisations and a 5-page Power BI dashboard.
Enterprise — the second largest segment by sales activity — recorded a net loss of ($614,545). Every Enterprise sale was costing more than it brought in.
Case Study Spotlight

From Data to Decision

When the dashboard went offline — and everything stopped

At The GTC Group, performance data lived across five disconnected platforms — CRM, email marketing, social media and website analytics. There was no single view of how the business was performing week to week, and every meeting started with someone manually pulling numbers from different systems.

I designed and built a Power BI dashboard that changed that. Connecting Dynamics 365, Mailchimp, Metricool, Google Analytics and a structured Excel tracker into one unified view, with custom DAX measures and a structured meeting workflow tool — leadership could walk into every weekly and monthly meeting with real numbers rather than guesswork.

The real proof of its value came when I went on annual leave. Without access to the dashboard, the team fell back to manually retrieving data from the CRM. The weekly leadership meeting could not run as normal, and the CEO immediately directed that all reporting tools must be cloud-accessible and never dependent on a single person.

That moment confirmed what good data work should do — it should become so essential to how an organisation operates that its absence is immediately felt.
