ASO7 Senior Data Analyst

South Australia Police · Intelligence & Probity Unit, Ethical and Professional Standards Branch (EPSB) · Adelaide, SA

I lead data analysis for the Ethical and Professional Standards Branch. My work turns complaint, investigation and workforce data into reports and advice that executives and oversight bodies can act on, and I build the tools that make that reporting repeatable.

• ·Produce the quarterly Use of Force and Vehicle Pursuit statistical reports for SAPOL executives, with a written method so every quarter can be reproduced and checked.
• ·Led an end-to-end review of the branch's complaint administration workflow, from receipt to file closure, built from team interviews and the team's own procedure notes, with findings and recommendations for branch leadership.
• ·Analysed a full financial year of hand-issued expiation notices for the Expiation Notice Branch, using a reproducible Python and Power BI pipeline and reporting only what the data can support.
• ·Built a Python client and web console for the complaint-management system's REST APIs, covering more than 1,100 endpoints, so records can be queried and checked by script rather than by hand.

• ·Designed and ran a Microsoft 365 Copilot workshop for EPSB staff, and rebuilt one of the branch's intranet pages as an accessible tile layout.
• ·Keep core data as the single source of truth for management information, strategic planning and parliamentary reporting.
