I turn messy operational data into clean, trusted pipelines — and increasingly, into AI systems that act on it.
Data and IT professional with a Graduate Certificate in Data Analytics (QUT) and the Databricks Certified Data Engineer Associate credential. Hands-on across enterprise application support, systems integration, and business reporting.
At AME Systems I integrated Siemens Capital with enterprise systems and automated data synchronisation in Python & SQL. Now, through Grampians.ai, I build AI and data engineering solutions for regional businesses — comfortable with stakeholders at every technical level.
